The recipe is from Dorie Greenspan's Baking: From My home to yours and it produces a tender, light cake that I loved. There is also loads of citrusy sparkle in there that simply makes the muffins shine.
Outside of these small touches, its your standard muffin recipe. You line 6 muffin tins with paper (I got 8 muffins but then I have tiny tins!). Then you mix up the liquids whisking together in this order: 1/4 cup orange juice, 1/4 cup buttermilk, one egg, 1 1/2 tbsp honey and 50 grams melted and cooled butter.
Next the dry ingredients. Rub 2 tbsp sugar with zest of a lemon. Mix in 1 cup plain flour, 1 tsp baking powder, a pinch of baking soda and another pinch of salt. Pour the liquid ingredients over the dry ingredients, stir to mix and finally add 1/2 cup fresh blueberries.
Divide the batter among muffin cups, filling them 2/3rd the way and bake for around 20 minutes or until a toothpick inserted in the center of the muffin comes out clean.
