I had no idea that different types of oils perform best at specific temperatures. Heating them beyond their best temperature or smoke point can change the flavor of your food and also change the healthiness of the oil in food preparation. Knowing what oils perform best at specific temperatures will help you in your vegetarian meals preparation and how well you will enjoy cooking and eating them.
- Oils with high smoke points, such as corn, soybean, peanut, sunflower and sesame, are good for high-heat frying and stir-frying.
- Olive, canola and grapeseed oils have moderately high smoke points, making them good for sautéing over medium-high heat.
- Oils with low smoke points, such as flaxseed and walnut, are best saved for use in salad dressings and dips.
Wholefoods has a great article about the different types of oil and how best to use them: http://www.wholefoodsmarket.com/recipes/food-guides/cooking-oils
