Ingredients
100g active or discard sourdough starter
120g whole milk (or buttermilk)
100g granulated sugar
50g brown sugar
1 large egg

1 tsp vanilla extract

Instructions
Mix the Wet Ingredients
1. In a large bowl, whisk together sourdough starter, milk, egg, sugars, melted butter, vanilla, and optional lemon zest.
2. Stir until smooth and well combined.
Add Dry Ingredients
3. Sprinkle salt, baking powder, and baking soda evenly over the surface.
4. Add flour and gently fold until just combined. Do not overmix.
5. Gently fold in the blueberries. If using frozen, toss them in 1 tsp flour before adding to prevent bleeding.
Rest the Batter (Optional but Recommended)
6. For enhanced flavor and texture, cover and refrigerate the batter overnight (8–12 hours).
7. If short on time, you may bake immediately.
Bake
8. Preheat oven to 375°F / 190°C. Line a muffin tin with paper liners or grease well.
9. Spoon batter evenly into the 12 cups, filling each about ¾ full.
10. Sprinkle tops with coarse sugar if desired.
11. Bake for 20–24 minutes, until golden and a toothpick comes out clean.
12. Let cool in the tin for 5 minutes, then transfer to a wire rack.
Visual Cues
Muffins should rise with rounded tops and golden edges.
Interior crumb should be soft, tender, and gently marbled with berries.
Why This Works
The sourdough starter (even discard) gives these muffins a tender, moist crumb with depth of flavor that plays beautifully with sweet berries. A long chill encourages hydration and rise — making this recipe ideal for prep-ahead mornings.
