How to make sweet popcorn
Heat oil and test kernels in a heavy pan.
Heat 3 tbsp (45 ml) vegetable oil and three popcorn kernels in a large, heavy-bottomed pan with a lid. When all three kernels have popped, the pan is hot enough to add the rest.

Available options:
+ Hold the lid on for a few minutes. See if you notice any oil coating on the lower side of the pan.;
+ Canola oil or another vegetable oil with a medium or high smoking point works best. If you're using microwave popcorn, just microwave the bag and skip down to melting the butter and sugar.;
+ To test kernels, place them on a heat-safe surface and wait until they turn golden brown. Cook the popcorn until the kernels begin to pop.;
+ Place the pan in the oil and let the kernels soak for 30 minutes. When all kernels have popped, the pan is hot enough to drop the popcorn.;
