Preheat oven to 400˚F. In small saucepan, combine butter, olive oil, salt, cayenne pepper and water; bring to boil. Add flour all at once; stir until mixture forms a smooth ball. Cook over low heat until mixture is drier but still smooth. Put mixture into mixing bowl; beat in eggs, one at a time. Stir in BelGioioso Asiago and BelGioioso Parmesan. Drop spoonfuls of batter onto greased cookie sheet. Bake 20 minutes or until slightly browned and firm. Makes 30 puffs.
