WHITE CHOCOLATE POPCORN
Ingredients
6 ounces of nestle white chocolate chips
2 (3 1/3 ounce) bags popcorn (NOT buttery kind)
Directions
Melt the chocolate in a double boiler or in the microwave. (Watch it closely if you use the microwave).
Microwave 2 bags of popcorn or pop about 7 oz. popcorn kernels.
In a large tub, (or 2 large bowls) drizzle melted white chocolate over popcorn. Mix and fluff as you go. Your looking for a light coat of chocolate on the popcorn -- too much will make the popcorn soggy and spongy.
Let popcorn cool in the refrigerator until the chocolate hardens. This is a great time to scoop servings of the popcorn into large ziplock baggys for easy storage.
NOTE: Peanut Butter White Chocolate variation;
1/2 cup peanut butter
3/4 cup powdered sugar
1 tablespoon milk
Combine ingredients. Add more sugar or milk to create drizzle consistancy.Drizzle over popcorn. Then drizzle white chocolate over that; Refridgerate until sets.
