A bright, rustic bake with a touch of sweetness. This naturally leavened focaccia is light and airy, topped with juicy raspberries, fragrant lemon zest, and a sprinkle of sugar that caramelizes as it bakes topped with a lemon glaze. The tang of sourdough balances the fruit's sweetness, making it perfect for brunch, afternoon tea, or a not-too-sweet treat any time of day. (Baked as an 8x8 serving).
