If you are a Meyer lemon fan, this recipe is for you! It is all about the lemons, their sweet, slightly floral essence in the spotlight, with nothing more than a flaky buttery crust to serve as a stage. Meyer lemons come into season in late Fall and early winter. They are a hybrid citrus, a cross between a citron and a mandarin, and are characteristically brighter, sweeter, and less acidic than other varieties of lemon. This tart is delicious on its own, and truly needs nothing more than a light dusting of powdered sugar, but if you want to dress it up, you could top it with freshly whipped meringue, meringue cookies, seasonal berries or even a drizzle of honey.Yields one 9"-10" tart.
