Beat white sugar and butter together in a bowl using an electric mixer until creamy and smooth. Add eggs, egg yolk, soured milk, and lemon zest; beat until smooth, scraping down sides of bowl as needed.

Mix rice flour, cornmeal, baking powder, and salt in a bowl; slowly stir flour mixture into creamed butter mixture until just mixed. Gently fold in blueberries. Pour batter into the prepared muffin cups, filling each about 3/4 full. Sprinkle each muffin with raw sugar.

Bake in the preheated oven until a toothpick inserted in the center of a muffin comes out clean, 18 to 20 minutes.
