The rind, or peel, of a lemon consists of two layers—the yellow zest (or the flavedo), and the white pith (albedo). The zest—where you’ll find all of the fruit’s aromatic oils—lends lemony fragrance to anything it graces, without the pucker.
Finding a suitable substitute for lemon zest in recipes can be tricky, but not impossible. Lemon oil, made from nothing but cold-pressed lemon rinds, is probably the most accurate substitute, taste-wise; but, if you’re unable to source a lemon, it’s probably also unlikely you have a stash of lemon oil. Here are some tips on how to utilize non-lemon lemon substitutes, to zesty effect.
