Wash the celeriac carefully, finely slice (ideally with a mandolin) and lay the slices on kitchen paper.

Sprinkle a little olive oil on the cooking plate and bake the slices of celeriac for about five minutes until they are crunchy, being careful to turn them regularly so that the lateral heat can do its work.

Place the slices on a cedar board and sprinkle them with the sea salt flakes for a delicious, healthy and low-fat snack.
