Your recipe sounds like it's pretty similar to what I remember....it wasn't really a cake, but is was kinda like a super rich "extremely moist" cake...I guess that's why they called it a "pudding"......I never like persimmons until I tried that cake...holiday time always brings back memories of that dessert.....it has been years since I had some. My mom lost the recipe years ago, but your recipe looks a lot like what I can remember....it was in a mold, and steamed the way you said....I bet it is delicious! I'm pretty sure it did have brandy or rum or bourbon though..... Sure wish I had a piece...or two (so my wife could try it too!!) Maybe we can try to make it, but I sure would love to find a company that sells it already made.
