16 c. or 1 gallon of popped corn
1/2 cup melted butter
1 cup brown sugar
1/2 tsp. salt
1/4 cup corn syrup
1/2 tsp. baking powder

Put 3 1/2 liters of popped corn in a large paper bag (no unpopped kernels).

Combine butter, sugar, salt, and corn syrup. Microwave 2 minutes, stir and repeat.

Add baking powder, stir it into the mixture, and pour over popcorn in the bag.

Close and shake. Microwave 2 minutes, shake and repeat.

One time, when out of brown sugar, and desperate for some kind of candied popcorn, I used white sugar and added a couple of teaspoons of cinnamon. It worked wonderfully as the candy coating cooks to a crunchy shell in the microwave. You can add any flavoring or colors that you want with good results.
