Preheat oven to 400F. Grease a cookie sheet and set aside. Core an apple and quarter. Add apple to a blender or food processor with a
splash of water and pulverize into the consistency of applesauce, adding a touch more water if necessary and set aside. In a mixing bowl, whisk flour, baking powder and a pinch of salt. (You can also add a little raw sugar or raisins for a sweeter biscuit, 1 tsp cinnamon or fresh rosemary for a savory biscuit here). Add applesauce 1/4 cup at a time until the batter is moist (wetter is better; you should use most of or all of the applesauce). Drop large spoonfuls on the cookie sheet and bake 10-13 minutes, or until firm to the touch and lightly golden on the bottom and edges.
