I was making those large flat string beans last night, the ones i believe are called Italian beans - they're light green and cook up bright green, are about half an inch wide and a longer than the regular ones. It made me crave a dish my friend's mother made back in the 70s or late 60s.
I remember it has some white sauce, which was not bechamel, it was much lighter, and i think may have been buttermilk - though it could have been sour cream or cream. I don;t know what else there was in it, but it tasted like more than just buttermilk and beans. \
Does anybody have such a recipe? I don't know where she got it, maybe from a magazine or a cooking show (back then there was just julia child, the galloping gourmet and joyce chen I think).
Would love to find it.
