Preserved lemon is a kitchen workhorse that easily moves to the bar. Here, it’s muddled with sugar and fresh lemon slices to release a light bitterness, harmonizing the sweet, the saline and the acidic. It appears once more, alongside olives and more fresh slices in the edible and fragrant garnish. While you can and should use both the preserved lemon rind and pulp (the pulp adds more welcome salinity and texture), use only the rind for the garnish. And, if you’d like to make this nonalcoholic drink alcoholic, add a splash of vodka, gin or, if you’re looking to triple down on the lemon flavors, limoncello.
