Is it really the laidenfrost effect that prevents food from sticking to hot stainless steel pan?

Is the Leidenfrost effect truly responsible for preventing food from sticking to a hot stainless steel pan? Consider the following points:

  1. The weight of the food might be too great for the Leidenfrost effect to create a sufficient lift.
  2. Foods like scrambled eggs can cool the pan almost instantly upon contact.
  3. If this is the case, what role does oil play when there isn’t sufficient heat?

    The Leidenfrost effect is indeed an interesting phenomenon, but it might not fully explain why food doesn’t stick to a hot stainless steel pan. Let’s break down your points:

    1. Weight of the Food: You’re correct that the weight of the food can negate the Leidenfrost effect. When food is dropped onto a hot surface, it may not have enough vapor to create that insulating layer if it’s heavy enough.

    2. Cooling Effect: When you add food like scrambled eggs to a hot pan, they can cool the surface almost instantly. In this case, the pan’s temperature can drop below the boiling point of water where the Leidenfrost effect wouldn’t be in play. This is why preheating the pan and using the right temperature is crucial for achieving a good sear without sticking.

    3. Role of Oil: The oil plays a significant role in creating a barrier between the food and the pan. Even if the pan isn’t extremely hot, the oil can fill in microscopic imperfections in the pan’s surface, increasing the effective non-stick property. The oil also helps to conduct heat evenly, which can prevent sticking when cooking at high temperatures.

    So, while the Leidenfrost effect might contribute under specific conditions, the combination of pan temperature, oil, and food moisture all work together to minimize sticking.
