Grilled Pineapple Upside-Down Cake

When pineapple caramelizes, whether on the grill or in the oven, its bright, tart flavor mellows to something warm and sweet—a neat trick that has long been the calling card of traditional pineapple upside-down cake. My grandmother’s version, with its canned pineapple rings, was one of my dad’s all-time favorite sweets. It’s one of mine, too, but when I make it, I start with freshly grilled pineapple to double the caramelization effect and add a splash of bourbon to drive the point home.
