During the 1930s depression my Grandma used to make "Pumpkin pie" from several things, and they all looked and tasted good. She used pumpkins, squash, sweet potatoes, carrots, pinto beans!!!!! Almost any veggie or fruit that could be mashed and cooked. With the addition of all those spices, eggs and milk, the original veggie taste couldn't be identified. If she said it was punkin, looked like punkin, smelled like punkin, tasted like punkin then it WAS a punkin pie and you ate it and liked it. And I suspect that the addition of flour or some other binder would make some neat cookies.
PuNkin was what came out of the garden.
PumPkin was what came out of cans!!! That P in it meant you had to spend money you couldn't afford on buying what you could raise.
