Meanwhile, pop the popcorn: First, place a large mixing bowl near the stove. Pour the oil into a large, heavy-bottomed pan with a lid. Turn the heat up to medium, add 2 kernels of corn, and cover. Once the kernels pop, remove the lid and pour in the remaining popcorn kernels. Cover the pot and give the pot a little shimmy to distribute the kernels evenly.
Toast the nuts: Once the oven has preheated, arrange the almonds (or other nuts) in a single layer on the parchment paper. Roast the nuts in the oven for 7 to 10 minutes, until fragrant. Keep an eye on them so they don't burn. If you're using whole nuts, chop the toasted nuts into small pieces on a cutting board.
Preheat oven to 350 degrees Fahrenheit. Line a rimmed baking sheet with parchment paper.
