KIDNEY WITH SOUR GRAVY.

Take 2 kidneys cut fine, freshen in water for 1 hour, adding a little soda. Take a heaping tablespoonful of lard, let it get hot, add 2 heaping spoonfuls of flour and keep stirring until a brown color; add a good sized onion cut fine and stew in the browned flour until soft, then add water or any kind of gravy or broth. Season to taste with salt and pepper and a slice of lemon. Squeeze out the kidneys and boil in the gravy until done; add a little vinegar to taste.
