When Should You Add Blueberries To A Muffin Mix?
Blueberries should be added to a muffin mix after combining the dry and wet ingredients and just before folding in any mix-ins like nuts or chocolate chips. This prevents the blueberries from sinking to the bottom during baking and ensures they are evenly distributed throughout the muffins. Tossing the blueberries in a bit of flour before adding them to the batter can also help to prevent sinking.
