And of course do whatever you want in the kitchen. However, some techniques appear to be more scientifically sound than others. At least for the fries.
30 degrees
Students from Edge Hotel School at the University of Essex and Samuel Whitbread School in Bedfordshire decided to search for the scientific success formula for baked potatoes. This may sound silly, but they still create the recipe for recipes. Whether or not French fries will work, it turns out, depends largely on the way you cut them. In the future, first cut the potatoes in half lengthwise, and then cut in half again at an angle of 30 degrees. This way you can improve the frying surface and thus take the potatoes to a higher level. More work, but then you also have something.
