Deep frying involves submerging a food in hot oil. The ideal temperature is around 350-375Â°F (176-190Â°C). When a food is submerged in oil of this temperature, its surface cooks almost instantly and forms a type of âsealâ that the oil cannot penetrate. At the same time, the moisture inside the food turns into steam, cooking the food from the inside.
