Patty pan squash are flatter, and they have a much smaller seed cavity. I kept picking the scalloped squash smaller and smaller, but regardless of how young I picked them, they still had a large seed cavity. Larger seed cavity means less flesh for eating. We're still saying that we're going to use the scalloped squash for stuffing, but we haven't done it yet. Unless we discover some really awesome way to cook these little darlings, they won't be in our garden again, regardless of how cute they look. When we don't eat something, it means we don't pick it, which means it just gets over-ripe and eventually gets fed to the chickens. And that just makes me feel guilty. And who needs that?
