Question: can you make a roux with bacon grease?
Answer: Making a roux is not difficult. ... In simple terms, a roux is equal parts cooked fat and flour. It's used to thicken soups, stews, and sauces; and in the South (and particularly New Orleans), it's famously used in Gumbo and Étouffée. You can use any kind of cooking oil, butter, or bacon fat to make a roux.
