I've found that the two stage method works well for cutting down on the loss of crispness.
You first cook the fries at a lower temp, say 320F, to get the insides cooked. Then, after cooling, cook the fried a second time at a higher temp, say 375F, to get the outside nice and golden brown.
The first cooking will remove some of the moisture from the inside that tends to migrate to the surface after cooking. That is a big factor in "loss of crispness." With the heat of the frying dissipating, there isn't much to keep the inside moisture from moving to the outside and messing with the crisp texture. |
