When I was newly married many years ago I made Christmas puddings for DH and his family from his grandmother's recipe, in her memory. Grandma had been born in England, and we always assumed that this was a family recipe.
I remember that it had dates, chopped suet, and probably nuts. I bought some pretty molds and steamed it for hours. I served it with a sauce made from orange juice and rind, sugar, and cornstarch, because that is what Grandma had done.
I think that I stopped making it when I discovered that the date cake recipe in my Better Homes and Gardens cookbook tasted nearly the same when I put the sauce on top, and was much easier and less messy to the stove top.
Maybe I'll get the recipe out and try this again. It certainly was delicious!
