Peanut oil (So that’s why the fries at Five Guys taste so good…)
Peanut oil is ideal for deep-frying because it does not absorb the flavor of foods cooked in the oil and can reach a very high temperature, which results in lower oil pick up and keeps the outside of the food crispy and the inside moist.
Refined peanut oil - which is bleached and deodorized - does not cause an allergic response, even in severely allergic individuals, as the refining process removes the allergic protein component of the oil.
Gourmet, roasted, aromatic oils are not refined and impart a strong peanut aroma and flavor to many foods. They also provide significant levels of vitamin E.
