Toasted sesame oil is much more fragrant than untoasted sesame oil. Be sure to check a recipe before using one or the other when cooking. If you do not have untoasted sesame oil, you can replace it with a mixture of one-third toasted sesame oil and two-thirds peanut or canola oil. To obtain the equivalent of 1 tbsp (15 ml) untoasted sesame oil, use 1 tsp (5 ml) of sesame oil mixed with 2 tsp (10 ml) peanut or canola oil.
