Popcorn is one of the cheapest snacks for a crowd, but it is easy to make far too little or a mountain that goes stale. This calculator works out the kernels for your guests.
How much per person?
- Snack or side: about 3 to 4 cups of popped popcorn per person.
- Movie night with big appetites: 6 to 8 cups.
- Party bar with toppings: about 4 cups, since guests mix it with other snacks.
For 10 guests at 4 cups: 40 cups of popcorn.
Kernels to pop
Good popcorn kernels expand about 30 to 40 times in volume. A common rule is that ½ cup of kernels makes about 16 cups of popped popcorn:
kernels = popped popcorn ÷ 32
For 40 cups: 40 ÷ 32 = 1¼ cups of kernels. Old or dried-out kernels pop less; store them in an airtight jar.
Batches and oil
A large stovetop pot or a home popcorn machine typically handles about ½ cup of kernels at a time, so 1¼ cups takes 3 batches. Use about 1 tablespoon of oil per ½ cup of kernels for stovetop popping, an oil with a high smoke point such as canola, coconut or peanut. Air poppers need no oil.
Stovetop method
- Heat the oil with 3 kernels in a heavy pot over medium-high heat.
- When those pop, add the rest in an even layer, cover and shake gently.
- Leave the lid slightly ajar to let steam escape for crispier popcorn.
- When popping slows to 2 to 3 seconds between pops, pour it into a bowl immediately.
Seasoning ideas
Melted butter, fine popcorn salt, grated parmesan, nutritional yeast, smoked paprika, cinnamon sugar or melted chocolate drizzled after it cools. Add salt and seasonings while the popcorn is warm so they stick.
Cost
Kernels cost little: about a dollar or two feeds 10 people, far less than microwave bags or theater popcorn. A half cup of kernels weighs about 3.5 oz.
Safety note
Popcorn is a choking hazard for young children; many pediatric guidelines advise waiting until about age 4.
