Whether you are looking for a light afternoon snack or suffering from a case of the late night munchies, grilling popcorn puts a new spin on an old favorite. When it comes to popcorn, your grill can do just what a microwave and stove top can. Popcorn kernels are water-filled seeds, and when the grilling temperatures are right, the water turns to steam, rupturing the seed coat until it pops. If you can fire up a grill, you can make those kernels pop.
Add enough vegetable oil to coat the bottom of a disposable aluminum half-size baking pan. The average half pan measures approximately 10 x 12 x 3.
Pour a cupful of popcorn kernels into the baking pan.
Cover the baking pan loosely with aluminum foil.
Fire up your grill, and wait for the thermometer to read between 450 and 500 degrees Fahrenheit -- high heat.
Place the baking pan on the grill rack.
Give the baking pan a shake every 20 to 30 seconds with a pair of grilling tongs until you start to hear the kernels pop.
Grill the popcorn until the popping stops -- about 8 to 10 minutes -- and then remove the baking pan from the grill with a pair of cooking mitts. Season the popcorn to taste.
