How to Make Perfect Popcorn on the Stove: 8 Pro Tips

Good popcorn is light, crunchy and fresh, and it takes only five minutes on the stove with a pot, oil and kernels. Most problems, such as burnt kernels, chewy popcorn or too many unpopped ones, come from the wrong pot, wrong heat or trapped steam. Here is how the pros do it, with every step explained.

How popcorn pops

Each kernel holds a drop of water inside a hard, sealed shell. When the kernel reaches about 180°C, the water turns to steam, pressure builds to about 9 atmospheres and the starch inside bursts and puffs out. Kernels that are too dry or have a cracked shell will not pop; kernels heated too slowly leak steam and stay as “old maids”.

What you need (serves 2 to 3)

1/2 cup (about 100 g) of popcorn kernels, which makes a large bowl (about 12 cups popped)
2 to 3 tablespoons of oil with a high smoke point, such as coconut, canola, sunflower or refined avocado oil
Salt to taste; fine popcorn salt sticks best
A heavy-bottomed pot (3 to 4 liters) with a lid

8 tips for perfect popcorn

Use a heavy-bottomed pot with a lid, so heat spreads evenly and kernels do not scorch. A glass lid lets you watch.
Use the right ratio: for 1/2 cup of kernels, use about 2 tablespoons of oil.
Test the heat with 3 kernels. Heat the oil with 3 kernels and the lid on over medium-high heat. When they pop, the oil is ready.
Add the rest of the kernels in an even layer, cover, and take the pot off the heat for 30 seconds so that all the kernels reach the same temperature, then return to medium-high heat. They will pop at nearly the same moment.
Crack the lid slightly to let steam out; this keeps the popcorn crunchy instead of chewy.
Shake the pot gently over the burner as it pops so nothing burns.
Take it off the heat when the pops slow to about 2 seconds apart. Waiting for the last pop burns the batch.
Season right away while it is still warm, so salt sticks. Use fine salt or a little melted butter, and toss in a big bowl.

Fixing common problems

Chewy popcorn: steam was trapped. Crack the lid and pour into a wide bowl right away.
Burnt popcorn: the heat was too high or the pot was thin. Lower to medium heat and shake.
Many unpopped kernels: the kernels are old and dry. Store kernels in a sealed jar; add 1 teaspoon of water to a jar of old kernels, shake and rest for 2 days.
Salt will not stick: use fine salt and season while the popcorn is warm; a light spray of oil or melted butter helps.

Flavor ideas

Cinnamon and a little sugar, with a pinch of salt
Parmesan and black pepper
Paprika, garlic powder or nutritional yeast
Melted dark chocolate drizzle (see our chocolate story)
Butter with a pinch of cumin and sumac, or dried herbs and olive oil
Sweet and salty with a drizzle of honey

Healthy snack notes

Plain air-popped or lightly oiled popcorn is a whole grain with fiber (about 3.5 g per 3 cups) and few calories (about 90 to 100 for 3 cups). The calories rise quickly with butter, caramel and a lot of oil, and movie-theater popcorn can have several times more. Pop it yourself and season with spices to control salt and fat.

Safety

Whole popcorn can be a choking risk for children under 4, so do not serve it to very young children.
Never leave hot oil unattended, and keep the lid ready in case of splatter.
Be careful when lifting the lid; steam escapes quickly.

Storage

Keep unpopped kernels in an airtight jar at room temperature away from heat; do not refrigerate them, which dries them out. Eat popped popcorn the same day, or store in an airtight container for up to 2 days.

Frequently asked questions

Can I make popcorn in the microwave in a paper bag?

Yes. Put 1/4 cup kernels in a lunch bag, fold the top twice and microwave for 2 to 3 minutes until the pops slow to 2 seconds. Use a brown bag without staples.
