I thought I had discovered the strangest shortcut to homemade pickled onions.
It started with a batch of thick-cut August sweet Vidalia onion rings.
They were large, juicy, sweet, and perfect-looking. Normally, I would have reached for vinegar, salt, water, and perhaps a little sugar to make a traditional pickling brine.
But this time, I decided to experiment.
Instead of vinegar-based pickling liquid, I used something completely different:
Cold evaporated milk.
Then I added crushed cinnamon hard candies for sweetness and spice and finished the mixture with a heavy dollop of canned chicken spread.
I submerged the onion rings completely, covered the container, and put it away.
Fourteen days later, I opened it.
The result was not a new kind of pickle.
It was a very important lesson about the difference between marinating, pickling, and preserving food.
And if you’re considering trying something similar at home, there is one part of this experiment you absolutely need to know before you even think about tasting it.
First: This Was Not a Safe Pickling Brine
The biggest mistake in this experiment was assuming that completely submerging the onions in liquid would preserve them.
It doesn’t.
A proper pickling process relies on specific conditions, particularly sufficient acidity, along with appropriate salt concentrations and, for shelf-stable canned foods, a validated canning process.
This mixture didn’t provide those conditions.
Evaporated milk isn’t vinegar.
Cinnamon candy isn’t a substitute for an acidified pickling brine.
Canned chicken spread doesn’t provide the kind of preservation environment required for safely storing vegetables.
And simply keeping the ingredients cold doesn’t turn the mixture into a safe long-term preserve.
That’s especially important because the mixture contained dairy and cooked poultry, both of which are perishable foods.
So although the experiment is fascinating from a food-science perspective, the resulting 14-day mixture should not be tasted or eaten.
If you actually made this mixture and it has been sitting for 14 days, the safest choice is to discard it without tasting it.
What I Expected to See After 14 Days
When I first imagined the result, I pictured something unusual but edible.
I thought the sweet Vidalia onions might absorb the cinnamon flavor.
The evaporated milk might make the onions creamy.
The chicken spread might add a savory, almost umami flavor.
And perhaps the cinnamon candies would dissolve into a sweet-spiced liquid.
On paper, it sounded bizarre but potentially interesting.
But food preservation doesn’t work simply by combining ingredients that have strong flavors.
An ingredient can taste intense without being an effective preservative.
That’s the crucial lesson.
Flavor and preservation are two completely different things.
What Happened to the Onion Rings?
After 14 days submerged in the mixture, the onion rings would likely have undergone substantial changes in texture and appearance.
Raw onions contain a great deal of water.
When they sit in a liquid for an extended period, water and dissolved compounds can move between the onion tissue and surrounding liquid.
The onion’s original crisp texture would likely become much softer.
The thick-cut rings could lose some of their characteristic crunch.
Instead of snapping cleanly when bent, they could become limp and fragile.
The exact appearance would depend on temperature, ingredients, container conditions, and the onions themselves.
But one thing is certain:
This would no longer resemble freshly cut Vidalia onion.
The Evaporated Milk Was the Biggest Clue
Evaporated milk sounds somewhat similar to ingredients sometimes used in marinades, sauces, and creamy preparations.
But evaporated milk is fundamentally a dairy product, not a pickling liquid.
It is milk from which some of the water has been removed and then heat-treated.
That makes it useful in cooking, but it does not turn it into a preservation medium for raw onions.
Once opened, evaporated milk is perishable and needs refrigeration.
Putting onions into it doesn’t make either ingredient shelf-stable.
In fact, adding raw vegetables and chicken spread creates a complicated mixture containing multiple sources of nutrients that microorganisms can use.
That’s exactly the opposite of what you want from a preservation liquid.
And Then There Was the Chicken Spread
The canned chicken spread made the experiment even more problematic.
A commercially canned product may be shelf-stable while the unopened container remains intact and is stored according to the manufacturer’s instructions.
Once you open it and mix it into another food, that original shelf-stable status no longer applies to the entire mixture.
This is a common misunderstanding.
People sometimes think:
“The chicken came from a can, so it’s preserved.”
But that’s not how it works.
The commercial canning process is what makes the unopened product shelf-stable.
Once you open the container and combine the contents with other foods, you have created a new food mixture.
That mixture needs to be handled according to the storage requirements of its individual ingredients.
The chicken spread therefore didn’t protect the onion rings.
It made the mixture more perishable.
What Did the Cinnamon Hard Candies Actually Do?
The cinnamon candies were probably the most interesting ingredient from a flavor perspective.
Hard candies are mostly sugar with flavoring and coloring.
Once exposed to moisture, they gradually dissolve.
Inside the cold evaporated milk, the crushed candy would release sugar and cinnamon flavor into the liquid.
The result could become noticeably sweeter and more strongly cinnamon-flavored over time.
But again, sweetness isn’t the same thing as preservation.
A little sugar in a mixture does not automatically make it safe.
Proper food preservation requires carefully controlled conditions.
You can’t simply add a sweet ingredient and assume microorganisms won’t grow.
Why Vinegar-Based Pickling Is So Different
Traditional quick pickling works because vinegar provides substantial acidity.
That acidity changes the environment around the vegetables and helps inhibit the growth of many harmful microorganisms.
A typical refrigerator pickle recipe is deliberately formulated around an acidic brine.
That’s why vinegar is such a fundamentally different ingredient from evaporated milk.
If you replace vinegar with milk, you’ve removed one of the central preservation mechanisms.
You haven’t created a new kind of pickle.
You’ve created a refrigerated food mixture that lacks the characteristics of a conventional acidic pickle.
What About the “Completely Submerged” Part?
This sounds reassuring.
After all, the onions were completely covered.
Unfortunately, being submerged doesn’t automatically make food safe.
Submersion can reduce contact with air, but many microorganisms don’t require oxygen to grow.
Some of the most dangerous foodborne pathogens can thrive under low-oxygen conditions.
That’s why you can’t use “completely submerged” as a substitute for acidity, proper refrigeration, salt concentration, or a validated preservation method.
A food can be completely underwater and still be unsafe.
What If the Container Was Refrigerated?
This makes an important difference, but it doesn’t make the 14-day mixture automatically safe.
Refrigeration slows the growth of many microorganisms.
It does not sterilize food.
And refrigerated storage times depend on the specific food and preparation.
A mixture containing opened dairy, raw onions, and opened canned chicken spread should not simply be treated like a commercially prepared pickle.
Fourteen days is a very long time for an improvised mixture of perishable ingredients.
If you actually made this and it has been sitting for 14 days, don’t taste it to determine whether it is safe.
That’s especially important because dangerous contamination isn’t always accompanied by an obvious smell or appearance.
Why Smell Isn’t a Reliable Safety Test
This is one of the most important lessons from the experiment.
You might open the container and think:
“It smells okay.”
That doesn’t prove it’s safe.
Some microorganisms that cause foodborne illness don’t produce obvious odors, colors, or visible mold.
Likewise, an unpleasant smell doesn’t tell you exactly what organisms are present.
Your nose is useful for identifying obvious spoilage, but it isn’t a laboratory food-safety test.
So don’t use:
- Smell
- Appearance
- Taste
- “It looks fine”
- “It tastes normal”
as proof that an improvised 14-day preserve is safe.
What About the Sweet Vidalia Onions?
Vidalia onions are famous for their mild, sweet character.
That makes them excellent candidates for traditional pickling because their natural sweetness contrasts beautifully with acidic vinegar.
But the fact that an onion is naturally sweet doesn’t change the basic preservation requirements.
A sweet onion is still a fresh vegetable.
It doesn’t become preserved simply because it is:
- Thick-cut
- Sweet
- Completely submerged
- Refrigerated
- Covered with dairy
- Mixed with sugar
- Combined with canned food
Preservation depends on the environment created around the food.
Could This Have Been a Delicious Recipe If Prepared Differently?
Absolutely.
The individual flavor ideas aren’t necessarily bad.
Cinnamon and sweet onions can work together.
Creamy dairy and onions can work together.
Chicken and onions obviously work together.
Sweet and savory flavors can complement one another beautifully.
The problem was the preservation method, not necessarily the flavor concept.
Instead of trying to preserve onions for 14 days in a dairy mixture, you could use these flavors in a dish designed to be cooked and eaten promptly.
For example, sweet onions could be cooked with chicken and a small amount of cinnamon as a seasoning.
Or you could create a sweet-and-savory onion sauce using properly handled ingredients.
The key is to separate creative flavor combinations from food preservation techniques.
If You Actually Want Pickled Vidalia Onions
This is where a tested recipe is the better choice.
For refrigerator pickles, use a recipe specifically designed for refrigerator storage.
A typical quick-pickle approach involves:
- Vinegar
- Water
- Salt
- Sugar
- Spices
- Fresh onions
The vinegar provides the acidity.
The salt and sugar contribute flavor and can affect the preservation environment.
The onions remain refrigerated.
And, importantly, you should follow a recipe from a reliable food-preservation source rather than improvising the ratios if long-term storage is your goal.
For shelf-stable canned pickles, the requirements are even more specific.
Use a tested canning recipe and follow the processing instructions exactly.
Don’t substitute evaporated milk for vinegar.
Don’t add chicken spread.
And don’t assume that changing one ingredient won’t affect the safety of the finished product.
Why Improvising Preservation Recipes Is Riskier Than Improvising Dinner
This experiment illustrates a useful kitchen rule:
You can improvise flavors much more safely than you can improvise preservation methods.
If you’re making dinner, replacing parsley with cilantro probably changes the flavor.
Replacing one vegetable with another might change the texture.
Adding an extra spice may make the dish stronger.
But preservation recipes are different.
Changing the amount or type of acid can change the safety of the entire recipe.
Changing salt concentration can change the preservation environment.
Changing ingredients can alter water activity and acidity.
Changing processing time or temperature can affect whether a food is safe for storage.
That’s why food-preservation recipes should be treated differently from ordinary cooking recipes.
What Should You Do With a 14-Day Batch?
If you actually made this exact mixture and it has been stored for 14 days, the safest recommendation is straightforward:
Discard it.
Don’t taste the liquid.
Don’t eat one onion ring “just to see.”
Don’t rinse the onions and try to save them.
Don’t cook the mixture and assume cooking will necessarily eliminate every possible hazard.
And don’t serve it to anyone else.
Dispose of it carefully, then wash the container and any utensils or surfaces that came into contact with the mixture.
The fact that it was refrigerated does not turn an improvised 14-day dairy-and-chicken mixture into a validated preserved food.
What I Learned From the Experiment
The biggest surprise wasn’t what happened to the onions.
It was how easy it is to confuse submersion with preservation.
The onion rings were completely covered.
The mixture was cold.
The ingredients included sugar.
The chicken came from a can.
The onions were naturally sweet.
None of those facts, individually or collectively, replaced the need for a proper preservation method.
That’s an important lesson for anyone who enjoys experimenting in the kitchen.
Creativity is wonderful.
But preservation requires a little more science.
Frequently Asked Questions
Can I pickle onions in evaporated milk?
No. Evaporated milk is not a substitute for the acidic brine used in conventional pickling.
Can sugar preserve onions?
Sugar can play a role in certain preservation methods when used at appropriate concentrations, but simply adding sugar or candy to a food mixture does not make it safely preserved.
Does keeping the onions completely submerged make them safe?
No. Submersion alone doesn’t provide the controlled conditions required for safe preservation.
Is canned chicken safe after opening?
An unopened commercially canned chicken product can be shelf-stable when stored properly. Once opened and mixed with other ingredients, it becomes a perishable food and must be handled accordingly.
Can I eat the onions if they smell normal after 14 days?
No. Smell is not a reliable way to determine whether food is free from dangerous microorganisms.
Can I cook the mixture to make it safe?
Don’t rely on cooking as a rescue method for an improperly stored, potentially contaminated food. If you have an improvised mixture of perishable ingredients that has been stored for an excessive period, discard it.
What should I use for actual pickled onions?
Use a tested refrigerator-pickle or canning recipe that specifies the appropriate vinegar, salt, sugar, proportions, storage conditions, and processing method.
The Final Verdict
Fourteen days after placing those thick-cut August Vidalia onion rings into cold evaporated milk, crushed cinnamon candies, and canned chicken spread, I had learned something much more valuable than a new pickle recipe.
Not everything that looks like a pickle is a pickle.
The onions were submerged.
The mixture was cold.
The cinnamon candies added plenty of sugar.
The chicken spread came from a can.
But none of those things created the acidic, controlled environment associated with a properly prepared pickle.
The evaporated milk made the mixture perishable rather than preserved.
The opened chicken spread added another perishable ingredient.
The cinnamon candies added sweetness and flavor but weren’t a replacement for vinegar.
And 14 days was far too long to treat this improvised combination as though it were a conventional refrigerator pickle.
If this was a real experiment sitting in your refrigerator right now, don’t taste it. Discard it.
But there’s a positive lesson hidden in the failure.
The flavor idea can still inspire a perfectly good meal.
Sweet Vidalia onions, cinnamon, creamy ingredients, and chicken can potentially be combined into a cooked dish where each ingredient is handled safely.
Just don’t confuse a creative marinade or sauce with a preservation method.
When it comes to preserving food, the safest approach isn’t necessarily the strangest or most creative one.
It’s the tested one.
So I’ll keep the cinnamon candies for dessert, the evaporated milk for cooking, the chicken spread for sandwiches, and the Vidalia onions for a properly prepared pickle.
Some kitchen experiments are worth repeating.
Others are best remembered as a lesson.
This one belongs firmly in the second category.
