Sesame Oil

There's toasted sesame oil, refined sesame oil, and unrefined sesame oil.

Refined sesame oil basically works like canola or vegetable oil. It has a very light sesame flavor, and a light color.

Unrefined sesame oil can be cooked with a bit, but things generally taste better when the sesame oil is added at the end as a seasoning. It tends to have a better flavor when it hasn't been used as the cooking oil, and doesn't have that high of a smoke point. And this is pretty much what everyone buys when they go buy sesame oil at the store for general use.

Toasted sesame oil has an even stronger flavor and is even less suited to cooking with.
