I currently have an excess of yellow squash and I've decided to make steamed yellow squash pudding today which is a lot like a carrot pudding but no cinnamon or nutmeg, just ginger, allspice and mace. it's even better if you include some chopped crystalized ginger (like sugered ginger, here in LA it's called Ting Ting Jahe and you get it in the chinese market).
