Once the kernels pop, remove the pan from heat and pour in the remaining popcorn kernels. Cover the pot and give the pot a little shimmy to distribute the kernels evenly. Let the kernels warm for one minute.
Place a large serving bowl near the stove. Pour the oil into a large, heavy-bottomed pan with a lid (if you have a medium-sized Dutch oven, it's perfect for this). Turn the heat up to medium-low, add 2 kernels of corn, and cover.
