Osgood Pie is closely related to Chess Pie and Vinegar Pie.
Some people say it is Chess Pie with raisins added.
Others give a distinct recipe of egg yolk, sugar, and butter creamed together, with vinegar for tang (1 to 3 tablespoons depending on recipe) with stiffly beaten egg white folded in, and baked in a pie shell.
Some recipes add nuts, raisins and / or spices.
Osgood Pie is a very old pie, at least in North American terms. It is mostly forgotten now, though some families still like to serve it at Christmas.
There are many speculations as to where the name "Osgood Pie" comes from. Some think it could be short for "Oh so good." Some think it's short for "Ozarks." None of the speculation seems to be that it might simply come from a family name, such as Osgoode.
Occasionally spelt "Ozgood", but that may be someone trying to reinforce the claim of the name being related to "Ozark."
