Last year, I deep-fried a turkey and I bought a 5 gallon container of peanut oil.
When the turkey was done, I strained the oil and put it back into its container. I even topped off the container with some additional oil so there would not be an air pocket.
This weekend we are doing an Oktoberfest and I want to fry another turkey. My wife insists I buy fresh oil, but I say this should still be good.
Does anyone know definitively whether peanut oil goes bad after a certain time (assuming its properly stored)?
