Candying lemon peel is a four-day process, but it keeps for a long time, and you’ll find other uses for it—I promise. Try it in cakes, sorbets, ice cream, and salads.
Using a vegetable peeler, peel the zest off the lemons in lengthwise strips. (Store the lemon flesh in the refrigerator for another use.) With a paring knife, scrape off any white pith from inside the strips of lemon peel.
