Step 4: Peeling the Lemon
Using a vegetable peeler or a paring knife, carefully peel the lemon. The goal is to avoid getting any of the pith (the white part) with the peel, as you want the oils in the peel. The pith will impart an unpleasant bitterness in the final product. If you peel off too much, you can always scrape off extra pith.
