If you want to eat potato slices, cut them into slices, and if you want to eat potato strips, cut them into strips. But there is a difference between slicing and cutting strips. The slices have to be thinner, so they'll be crispier when you fry them. Cutting strips should be slightly thicker, note: is slightly thicker. Then if the oil is hot, you can put the potatoes into the frying. Be careful that the oil temperature is not too high, it will burn. When you see the color becomes golden brown, fish out, put on a plate lined with oil-absorbing paper, and then sprinkle a little salt or sugar, according to your taste. Be careful of getting burned by the oil during the operation. This is the case, seems to be a little long-winded, sorry ah, oh ~
