The best popcorn, unsurprisingly, comes from professional poppers or stovetop recipes. But there's a trick to make your basic, microwavable bags of popcorn even better! Before you put the popcorn bag in the microwave, heat a cup of water on high for 1.5 minutes. Remove the cup, put in your popcorn, and microwave as usual. The popcorn will be fluffy and moist, with less of a chance of burning and less un-popped kernels.
