Toss fresh blueberries in a light dusting of flour before adding to the batter to prevent them from sinking and ensure even distribution throughout the muffins.

Let buttermilk come to room temperature and mix with baking soda first to activate its leavening properties, creating a lighter, more tender muffin crumb.

Use an ice cream scoop with a release mechanism to create perfectly uniform muffins with minimal mess and consistent sizing.

Do not overmix the batter - stop mixing as soon as dry ingredients are just incorporated to prevent tough, dense muffins.

Sprinkle a light layer of coarse sugar on top of the muffins before baking to create a delightful, crunchy exterior that contrasts with the soft interior.
