Blueberry-Banana Muffin

If you use paper liners, the muffins keep their shape especially well when baked in a tin.

Very ripe bananas (with brown spots) add more sweetness and flavour.

Toss the blueberries briefly in the flour mixture first; they'll be less likely to sink while baking.

Ingredients should ideally be at room temperature so the batter combines more evenly.

Don't overmix; otherwise the muffins become dense instead of fluffy.

Fill the liners to about two-thirds; the muffins are done when a skewer or toothpick comes out almost clean.

For decoration, powdered sugar, a little cinnamon-sugar or a dollop of yogurt cream with fresh berries work well.
