Supreme Cream Puff: Fountain on Locust Owner Joy Christensen says this is the quintessential dessert for ice cream lovers, calling it �simple, elegant and delicious.� It starts with a 3-inch baked pastry shell that�s then filled with vanilla ice cream and topped with hot fudge. The key to this sweet treat is aged ice cream, sourced from Cedar Crest Dairy in Wisconsin, which has just enough milk fat to be thick and rich without sacrificing flavor.
