How to make popcorn snacks for kids
Grease a bowl, spatula, and baking dish.
Because the caramel is extremely sticky, you must prepare your tools and supplies. Use nonstick cooking spray to grease a large bowl, plastic spatula, and a 13-inch by 9-inch (33-cm by 23-cm) baking dish before mixing the popcorn.

Possible answers: --Use a pastry brush to ensure the surface is clean, as grease will be sticky if the popcorn gets wet. If you have a whole popcorn roll pan, set one aside while you work. --Slice the bottom of the microwave to meet the base of the bowl. You want a mini microwave to produce popcorn crispier, more evenly distributed and more healthy. --If you prefer, you can use softened butter to grease your tools and supplies. Mix the popcorn and pretzel pieces. --If you're using a regular bowl for the popcorn, line the bottom of the bowl with 4-inch (10-cm) shortening. Preheat your oven to 350 f (177 c).
The answer is:
If you prefer, you can use softened butter to grease your tools and supplies. Mix the popcorn and pretzel pieces.
