I am making a dish for Christmas that uses marshmallows, and since I saw a cook on PBS cooking marshmallows last month, I decided to make my own. Here is the recipe I used, Homemade Marshmallows | Taste of Home Recipes. I made 1/2 the recipe and ended up with a 9x13 in. pan with marshmallows about 3/4 in. thick. This morning, I sliced them and dusted them with powdered sugar, and they are the best marshmallows I have ever had.
