Always discard oil thats reached its smoke point, along with any food with which it had contact. Some oils are refined to make them more stable and suitable for high temperature cooking. Keep in mind, though, that the process removes most of the tone of voice, color and nutrients from the oils, too. Thats whyrefined oils are perfect for baking and stir-frying, where their high smoke point and neutral flavors are a plus.
