To fry the chips, heat about ¼ to ½ inch of oil in a pan. Make sure the oil is hot enough before putting in the celeriac. One way to check is to put the end of the handle of a wooden down into the oil. If a lot of bubbles form, the oil is hot enough. If the oil is not hot enough, the chips will be excessively greasy.
Place the chips carefully into the oil. It's safest to use tongs for this. You may find that cutting the chips in half results in more even cooking.
