Can I use discard that's been in the fridge for a while?

Yes! Refrigerated discard can be used for up to 2 weeks after feeding. Older discard might be more sour, which can actually add an interesting flavor dimension to your muffins. Just make sure there's no mold or off-putting smell, and bring it to room temperature before using. If your discard has a layer of liquid on top (hooch), either stir it in or pour it off – both ways work, but stirring it in will give you tangier muffins.

Why didn't my muffins rise as much as expected?

The most common culprits are inactive leavening agents or overmixing. Even though we're using sourdough discard, the rise primarily comes from the baking powder and soda. Test your leavening agents by putting a little baking powder in water (it should fizz) or baking soda in vinegar (it should bubble vigorously). Also, remember that overmixing develops gluten, which can lead to dense, tunnel-filled muffins.

Can I make these muffins more sour?

Absolutely! Try these tricks: Use older discard (1-2 weeks old) Stir in any hooch that has developed Reduce the sugar slightly (by about 2 tablespoons) Let the batter rest for 30 minutes before baking Just note that very sour muffins might not be to everyone's taste – consider your audience!

What's the best way to incorporate mix-ins without them sinking?

Toss your mix-ins (like berries or chocolate chips) in a tablespoon of the dry ingredients before adding them to the batter. This coating helps them stay suspended during baking. Also, gently fold them in at the very end using as few strokes as possible to avoid overmixing.

My muffins stuck to the paper liners – help!

This usually happens when the muffins are still warm. Let them cool completely before unwrapping. If you're still having issues, try these solutions: Spray the inside of the paper liners with cooking spray Use parchment paper liners instead of regular paper ones Skip the liners and grease the pan well instead Let muffins cool for 5 minutes in the pan, then transfer to a wire rack

Can I use this recipe for mini or jumbo muffins?

Yes! For mini muffins, reduce the baking time to 12-15 minutes. For jumbo muffins, increase it to 25-30 minutes. Always use the toothpick test to check for doneness – it should come out clean or with just a few moist crumbs.

Instructions

Preheat the oven to 375°F (190°C) and line a 12-cup muffin tin with paper liners or grease it well.
In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt.
In a separate bowl, combine the sourdough discard, eggs, oil, milk, and vanilla, stirring until fully mixed.
Gradually fold the wet ingredients into the dry mixture, stirring gently until just combined—some small lumps are fine.
Evenly distribute the batter into the muffin cups, filling each about ¾ full.
Bake for 20-25 minutes, or until a toothpick inserted in the center comes out clean.
Let the muffins cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely.

Notes

Use sourdough discard that has been fed within the past week for the best results.
Allow ingredients to reach room temperature for better blending.
Avoid overmixing the batter to ensure soft, tender muffins.
Rotate the muffin tin halfway through baking for even browning.
