The link to food scraps shows us what to save, and mentions seeds of pumpkin and squash. I save not only the seed but all the gunk that surrounds them. You eat that stuff in cucumbers and zucchini, and it is good food. I put all of this into the blender with about a cup or two of water and blend until liquified. Then it is used in making breads. Add it as part of the liquid. The bread tastes wonderful.
