Lushly tart and bright honey hued nectarines get bathed in a sumptuously fragrant brown sugar, vanilla whiskey sauce and layered over a deeply nutty brown butter almond frangipane. All that nectarine and frangipane goodness gets wrapped in an all butter crust to create the most rustic summer galette. Drizzle this beauty with some salted caramel sauce and serve with some classic vanilla ice cream for the perfect summer dessert.
