Some of my recipes ask for 1/4-1/2 cup of red or white wine. DH has expensive wine that he got good deals on, but he will freak of I use it in cooking.
Today at the grocery store, I picked up 4 pack of very small bottles, about 1 cup each. It was same price as normal bottle of wine, but if I buy a bottle of cheap wine, it never gets all used.
Does anyone sell wine just for cooking?
