Grind up a cup or so of pellets, or soak if you don't have a coffee grinder or blender, but only in a minimal amount of water. add one or two eggs, a teaspoon of baking powder but you can do without and whatever veg/fruit you want but chop it up finely and don't add too much to start with. The consistency of the dough should be quite thick. If it is too thick add a bit more water, if it is too liquid, add more pellets. Spoon in the paper cups or just roll into rounds in your hands and bake for about 30 minutes at about 190C(gas mark 5)
