These savory little scones are packed with sharp Cheddar, Parmesan, and fresh spring onions. A splash of buttermilk keeps the crumb tender and moist, while a pinch of cayenne pepper adds a subtle background heat. They come together quickly by hand and bake up tall with a beautiful golden crust. Serve them warm right out of the oven with a pat of butter, or pair them with a steaming bowl of soup for a comforting lunch.
