Mix flour, baking powder, and sugar in a large bowl. Drop in your cool butter, then work it in with your fingers until it's crumbly with some tiny butter bits still there. Toss in the lemon zest. Pour in the milk and mix until you get a soft, sticky dough. Throw in a splash more milk if it doesn't come together.

Move the dish into your oven and let it bake for 25 to 30 minutes. Watch for bubbling fruit juice around the edges and a golden top.
