Onetime I had a job where I was working in a small family owned shop where I sold ice cream. I learned more there about what not to do while running a business than I will probably ever learn in college.
Recipe from Jeni& splendid book. I used Plush Puff& Gourmet Gingerbread Spice marshmallows. (Thank you, Justin!) I still don& own a kitchen torch so the marshmallows were toasted the old-fashioned way over my stove.
