One of the many wonders of grapeseed oil is its high smoke point, the temperature at which an oil starts to produce smoke. If heated beyond this point, it becomes flammable and will end up burning.
As a result, oils like grapeseed oil are ideal for any kind of cooking that calls for very high temperatures, such as frying and fondues. The fact that it doesn’t burn easily also means that grapeseed oil can be reused several times. Isn’t it about time you tried it with your French fries?
