Can you mix old and new cooking oil?
Mix With New Food52 says it’s possible to mix small quantities of old oil with new for better frying. “As oil breaks down, the molecules become less hydrophobic, which means they can come in closer contact with the food; thus, frying can happen more efficiently!
