Ingredients:

- 1/2 cup (1 stick) unsalted butter, softened (butter adds that lovely moistness to this Sourdough Discard Lemon Loaf)
- 2 large eggs (I use pasture-raised eggs whenever possible for richer flavor)
- 1 1/2 cups all-purpose flour (my favorite for the Sourdough Discard Lemon Loaf’s crumb)
- 1 tsp baking powder (an essential little helper for rising in this Sourdough Discard Lemon Loaf)
- 1/2 tsp baking soda (helps balance the acid from the sourdough discard and lemon zest)
- Pinch of salt (to round out the flavors in this Sourdough Discard Lemon Loaf)
- Zest of 2 lemons (fresh zest makes all the difference in this Sourdough Discard Lemon Loaf)
- 1/3 cup freshly squeezed lemon juice (for the perfect tang in this Sourdough Discard Lemon Loaf)

How to Make – Step by Step
1. Preheat your oven to 350°F (175°C). Grease a loaf pan or line it with parchment paper—this little prep step helps your Sourdough Discard Lemon Loaf come out perfectly and prevents sticking.
2. In a big mixing bowl, beat together the softened butter and sugar until creamy. This step is key to that moist, tender crumb that makes this Sourdough Discard Lemon Loaf so special.
3. Add in the eggs one at a time, beating well after each addition. The mix will look a bit shiny—that’s your cue that the Sourdough Discard Lemon Loaf batter is coming together nicely.
4. Stir in the sourdough starter discard, lemon zest, and lemon juice. You should already start smelling that fresh lemon zing, which is such a comforting sign that this Sourdough Discard Lemon Loaf is on its way to something delicious.
5. In a separate bowl, whisk together the flour, baking powder, baking soda, and salt. Gradually fold this dry mix into the wet ingredients until just combined—don’t overmix or your Sourdough Discard Lemon Loaf could turn tough.
6. Pour the batter into your prepared loaf pan and smooth the top. Pop it into your preheated oven and set a timer for about 45-50 minutes. When baking the Sourdough Discard Lemon Loaf, I usually peek at the 40-minute mark to check with a toothpick. It should come out clean or with only a few moist crumbs.
7. Once baked, let your Sourdough Discard Lemon Loaf cool in the pan for 10 minutes before turning it out onto a wire rack. The smell alone is worth that wait.

FAQs:
Q: Can I use my regular sourdough starter discard for the Sourdough Discard Lemon Loaf?
Absolutely! I’ve used discard from starters fed with different flours and it always works beautifully in this Sourdough Discard Lemon Loaf. Just make sure your discard isn’t overly tangy or very liquidy, or you might need to adjust the flour a little.
Q: How can I make my Sourdough Discard Lemon Loaf more moist?
Adding a bit more butter or swapping half the sugar for honey can add moisture. I also recommend not overbaking—try to check at 45 minutes, since every oven is a bit different.
Q: Can I freeze this Sourdough Discard Lemon Loaf?
Yes, you can! I slice mine before freezing and thaw slices as needed—they keep the texture and lemon flavor well.
Q: What if I don’t have fresh lemons?
Fresh zest and juice are best for the bright flavor in Sourdough Discard Lemon Loaf. However, in a pinch, bottled lemon juice and dried zest can work, but it won’t have quite the same punch.
Q: How do I know when the Sourdough Discard Lemon Loaf is done?
A toothpick inserted in the center should come out clean or with a few moist crumbs. The zest and lemon scent will also intensify during baking, which is such a helpful guide in your kitchen.
Q: Can I make mini loaves or muffins with this Sourdough Discard Lemon Loaf batter?
Yes! Just adjust the baking time down to 20-25 minutes and watch closely. Mini versions are great for portion control and lunchboxes.
Q: Does this Sourdough Discard Lemon Loaf freeze well with lemon glaze?
I recommend glazing after you thaw it for the best texture, since the glaze can harden or get sticky in the freezer.
