what kind of fat is in french fries
French fries Most French fries are produced from frozen potatoes which have been blanched or at least air-dried industrially.[9] Most chains that sell fresh cut fries use the Idaho Russet Burbank variety of potatoes. It has been the standard for French fries in the United States.[8] The usual fat for making French fries is vegetable oil. In the past, beef suet was recommended as superior,[4] with vegetable shortening as an alternative. In fact, McDonald's used a mixture of 93% beef tallow and 7% cottonseed oil until 1990, when they switched to vegetable oil with beef flavoring.[10][11] Starting in the 1960s, more fast food restaurants have been using frozen French fries.[8]
