I use 1tbsp Crisco shortening for every cup of chocolate morsels (that would be 2 tbsp per 12 oz bag). Microwave for 30 seconds, stir, then at 15 second intervals, stirring between until melted. Stick back in the microwave for 10 seconds when the chocolate starts to thicken up. I make chocolate covered pretzels every year out of the small Christmas shaped pretzels & they are my son's favorite! I just made buckeyes last night & always dip them using this method.
