In a large bowl, mix together the flour, cornmeal, 5 tablespoons of sugar, baking powder, baking soda, and salt.
Carefully add the blueberries to the bowl and mix them in.
In a small bowl, whisk the buttermilk, oil, egg, and lemon zest together.
Pour the buttermilk mixture into the large bowl with the flour mixture. Stir until everything is just moistened.
Fill the muffin cups with the batter, making sure each cup has an equal amount.
Sprinkle the top of the batter with the remaining 1 tablespoon of sugar.
Bake in the oven until the muffins bounce back when you gently press them, about 15 to 20 minutes.
After baking, let the muffins cool in the pan on a wire rack for 5 minutes.
Take the muffins out of the pan and let them cool on the rack for another 15 minutes.
