Rejuvenating my go-to "cheesecake" recipe, I add a spritz of orange juice and zest, and replace the graham cracker with a chocolate sandwich cookie. Orange and chocolate pair beautifully: the former is floral and sweet; the latter, deep and bitter. This is what you want to eat with friends in the sun, or as a solitary treat; the perfect balance between high and low, citrusy spritz and dark melancholy—as summer should be.
