Recipe Tips

Amount in one bag of popcorn. One 3.28 oz bag of popcorn contains 5 tablespoons of un-popped kernels or about 11 cups of popped corn. There are 3 ways to get popcorn for this recipe:

  1. Buy 11 cups of plain pre-popped popcorn.
  2. Pop 5 tablespoons of your own kernels.
  3. Pop a bag of plain microwave popcorn.

Marshmallows. Substitute large marshmallows for mini marshmallows with a 1:10 ratio. For this recipe use 200 mini marshmallows or about 3 cups.Either way, remember old marshmallows won’t melt well.

Corn syrup substitute. There are a few options though they may alter the taste, but not by much. Substitute a 1:1 ratio of maple syrup or honey. In the UK the closest substitute is “Golden Syrup”.

  • Make your own simple syrup: In a saucepan mix ¼ cup of water with 1 cup of granulated sugar. Simmer until the sugar has melted and makes a syrup.

Popcorn. Use any flavor of popcorn, but I prefer plain popcorn for this recipe. Kettle corn, salted popcorn, or lightly buttered popcorn work as well.

Don’t add extra popcorn or there won’t be enough caramel to hold them together. However, if you don’t add enough popcorn, the caramel will “melt” and it won’t hold its shape.

Easy cleanup. Grease your hands with cooking spray before forming the balls to prevent sticking.

Toppings. This popcorn really speaks for itself, but it can be fun to mix in a few colored sprinkles, little candies, chopped nuts, or mini chocolate chips. Do not add too many extras or the ratios will be off and the popcorn ball won’t stick together.

In a small saucepan, bring butter, sugar, 1/8 teaspoon salt, and 2 tablespoons water to a boil, stirring constantly. Working quickly, drizzle popcorn with sugar syrup, and toss. Spread popcorn evenly on prepared baking sheet. Bake, tossing occasionally, until golden and shiny, about 40 minutes.

How to revive stale caramel popcorn? ›

Resist the urge to toss out that bag of stale popcorn. If you're looking to breathe new life into the snack, spread it on a baking sheet and heat in the oven at 250°F for about five minutes. It should be as good as new!

Why put a whole egg in caramel popcorn? ›

While some people said that she added the egg to absorb extra heat, others had different views. "Whole eggs absorb excess heat so it's an easy way to regulate the temperature balance of the other ingredients," a user wrote.

Why is my caramel popcorn not crispy? ›

The longer you cook the syrup (the mixture of sugar and water the forms the base of the caramel sauce), the crunchier your popcorn will be. For very crunchy popcorn (my favorite!), stop cooking when you see the first wisps of smoke coming from the sugar mixture.

Why is my caramel popcorn soggy? ›

Baking the caramel-coated popcorn helps to set the caramel sauce. By skipping this step, the caramel corn will become soggy.

Why did my caramel popcorn turn out chewy? ›

Generally, the caramel will have a higher 'water activity' than the popcorn. As a result, if you leave the popcorn for a while, moisture from the caramel will migrate into the corn. This causes the popcorn to lose its 'crunch' and become soft and chewy.

What happens if you forgot the baking soda in caramel corn? ›

Baking soda is what makes caramel corn chewy with a bit of crunch and gives it the classic brittle texture. The baking soda also helps the mixture to increase in volume which ensures it covers all of the popcorn. It's an essential ingredient and without it you'll likely find the texture of the caramel corn to be off.

Is caramel popcorn the same as toffee popcorn? ›

Although similar, toffee and caramel are not the same. Toffee is made out of just caramelized sugar and butter, unlike caramel which contains corn syrup and sometimes milk or cream. As a result, toffee popcorn is more brittle and crunchy in flavor and has a distinct buttery taste.

Can you crisp up caramel popcorn? ›

Once coated, spread the popcorn on a baking sheet lined with parchment paper. If you prefer chewy caramel corn, let it sit until the caramel has hardened. If you prefer crunchy caramel corn, Preheat oven to 250 F. and bake for 30-40 minutes, tossing occasionally.

Why did my caramel popcorn crystallize? ›

A granule of sugar, over-mixing, or uncooperative clumps of sea salt can turn caramel from a glossy, shiny confection into a dull grainy heap of chewy, brown sugar crystals.

What to do if caramel popcorn is bitter? ›

Overheating the mixture

Follow the recipe carefully, and never melt your caramel on your stove's highest setting—it will cause the caramel to scorch and taste burnt. Once it gets a burnt or bitter flavor, it can't be saved. Luckily, sugar is inexpensive, so you can always start over!

Should I soak my popcorn before popping? ›

To make your popcorn pop better, try soaking the kernels in a bowl of water for 10 minutes and then draining them. Then, pop the kernels as usual. The extra moisture added to the kernels helps produce larger and fluffier popcorn. Another option is to keep the lid ajar if you're popping your popcorn on the stove.

How long does store bought caramel popcorn last? ›

Q: How long does the caramel corn stay fresh? A: Our delectable caramel corn remains fresh for several weeks when stored in a cool, dry place and in its original packaging. Stock up now to ensure you always have a crunchy, satisfying treat on hand!

What does sodium bicarbonate do to caramel? ›

The purpose of baking soda in the caramel is to react with the acid (the brown sugar and corn syrup), which creates tiny carbon dioxide air bubbles, which makes the caramel softer/lighter. It is neutralized by adding HCl. NaHCO3 + HCl → NaCl + H2O + CO2.

What happens when you add baking soda to pop? ›

– the science bit. The citric acid reacts with the carbonate in bicarbonate of soda to form carbon dioxide gas. These bubbles of carbon dioxide are what make your drink fizzy. You can find out more about carbonates and acids here.

What can I use instead of baking soda in caramel? ›

There are several pantry-friendly ingredients that you can use as baking soda substitutes, including egg whites, self-rising flour and even club soda. Or, you can use baking powder - and even a couple of extremely scientific sounding items that perhaps you just happen to have lying around - baker's ammonia anyone?
