My sister still makes Gran's Cran (her cranberry sauce) evry Thanksgiving, but I don't know the recipe.
Granny was from Russia, and was Dad's mom.
My mom, from Hungary/the former Yugoslavia (depending on when you mean) makes everything delicious with either bacon grease or sour cream, or both. She is now a great-grandmother, so I guess her stuff would count as SOMEBODY's grandmother's recipes!
I will look up the recipe for Rocket Crumple, our childish pronunciation of Rokott Krumpli, Hungarian for sliced potatoes. It's best described by Tibor Kalman, the late great artist. It involces cold sliced boiled potatoes, sliced strong kolbasz or Hungarian spicy sausage, sliced hard-boiled eggs, layered with more sour cream and butter than you would normally use in a year in the States. As it cooks, the juices from the sausage and all that butter permeate the potatoes and the eggs and it is the best food in the universe.
