Place 2 tablespoons oil and 2 to 3 kernels in a 3-quart or larger pot. Turn heat to medium-high and cover with a lid. When you hear these first kernels pop, add the remaining kernels and replace the lid. Using potholders, shimmy the pot around to keep the kernels moving as they pop. When several seconds pass between pops, remove from heat. Transfer to coated bowl. You should have about 8 cups popcorn.
