Sourdough Discard Zucchini Carrot Bread with Pistachios

You’ll love this light and fluffy Sourdough Discard Zucchini Carrot Bread with pistachios and an icing drizzle for perfect sweetness and texture.

Zucchini Carrot Bread Ingredients

This zucchini carrot bread batter is very similar to muffin batter. It’s super easy to mix. The key is to mix all the dry ingredients separately from the wet ingredients before combining. You also want to ensure your wet ingredients are the right temperature before mixing them together!

The Best Bread Pan for Zucchini Carrot Bread

I picked up this fantastic non-stick bread pan at Whole Foods, and I LOVE it. It’s perfect for any bread. Click here to get one.

For this recipe, it’s best to use a non-stick metal bread pan close to a 9x5x3 dimension. Here are a few more options I’d recommend:

  • Caraway Ceramic Bread Pan
  • USA Pan 1-pound loaf pan
  • Cuisinart Loaf Pan

Should you squeeze the water out of zucchini for bread?

In some recipes, you may need to, but in this recipe, you don’t!

In some quick sweet bread recipes, you might not need to squeeze the water out of zucchini for several reasons:

  1. Moisture Balance: I designed my recipe to accommodate the additional moisture from the zucchini. The zucchini’s moisture content can help create bread that is exceptionally moist and tender.
  2. Recipe Formulation: The amount of dry ingredients (like flour and sugar) in these recipes may be adjusted to account for the extra liquid from the zucchini. This ensures the batter has the correct consistency and the bread bakes properly.
  3. Desired Texture: Some zucchini bread recipes aim for a very moist, almost cake-like texture. The zucchini’s water content contributes to this texture, making the bread soft and tender.
  4. Simplicity and Convenience: Not squeezing the zucchini simplifies the recipe, making it more straightforward and quicker to prepare. 

Should zucchini be peeled before shredding for bread?

No, you shouldn’t peel the zucchini before grating it and incorporating it into the bread. I prefer to leave the skin on for fiber, but also for a pop of color inside the bread.

The zucchini skin is perfectly healthy, especially if you use organic zucchini. So skip the extra work and leave it on! Your bread will be prettier with it.

Don’t Over-Mix the Zucchini Carrot Bread Batter!

When making quick bread one crucial tip is to avoid overmixing the batter. Overmixing can result in dense bread rather than a light and fluffy loaf. The reason behind this lies in the formation of gluten.

Gluten, a protein present in flour, gives structure to baked goods. However, excessive mixing develops gluten strands, leading to a denser texture. To prevent this, gently mix the dry and wet ingredients until just combined, ensuring there are still some lumps and streaks of flour in the batter.

This technique allows the carrot zucchini bread to rise correctly, resulting in a tender crumb and a delightful eating experience.

My other quick bread baking tip is always to use a great, non-stick metal loaf pan.

Sourdough Discard Zucchini Carrot Bread with Pistachios

You’ll love this light and fluffy Sourdough Discard Zucchini Carrot Bread with pistachios and an icing drizzle for perfect sweetness and texture. This bread is ideal for any spring or summer get-together. Pair it with coffee or tea for a lovely afternoon snack.

  • Prep: 15 minutes
  • Cook: 1 hour
  • Total Time: 1 hour 15 minutes

Ingredients

  • 2 cups all-purpose flour
  • 1/2 cup sugar
  • 1/2 teaspoon baking soda
  • 1 teaspoon baking powder
  • 2 tablespoons potato starch
  • 1 teaspoon salt
  • 1 teaspoon cinnamon
  • 1/2 tsp ground ginger
  • 1/2 cup crushed pistachios
  • 1/2 cup carrots, grated
  • 1/2 cup zucchini, grated
  • 1/2 cup unsalted butter, room temperature soft
  • 1/2 cup sourdough starter, room temperature
  • 1 teaspoon vanilla extract
  • 1/2 cup whole milk, room temperature
  • 2 eggs, room temperature

Icing

  • 1/3 cup powdered sugar
  • 2–3 teaspoons whole milk
  • crushed pistachios

Instructions

  1. Preheat your oven to 350° F.
  2. Grease a non-stick, 5×9 (1-pound) bread pan with butter.
  3. Grate and measure out the carrot and zucchini.
  4. In a medium-large mixing bowl, combine the flour, potato starch, sugar, baking soda, baking powder, salt, cinnamon, ginger and pistachios.
  5. In a separate bowl, combine the carrots, zucchini, butter, sourdough starter, vanilla, whole milk, and eggs. Mix the wet ingredients until evenly combined.
  6. Gently fold the wet ingredients into the dry ingredients until everything is just combined. Do not over-mix. The batter should be thick, and it’s okay if there are some dry clumps.
  7. Scoop the batter into the bread pan.
  8. Bake for 40-50 minutes total. Rotate the pan halfway through.
  9. While the bread bakes, mix the icing together. Add the milk 1 teaspoon at a time, keeping the icing super thick but able to be drizzled. Crush or chop some pistachios to sprinkle on top the icing.
  10. Allow cooling for about 15 minutes in the pan, then slide the loaf out of the pan onto a cooling rack, allowing it to cool completely.
  11. Drizzle with icing and top with crushed pistachios.

    Could I use corn starch instead of potato starch? Or would you just leave it out?

    This sounds good, and I’d like to try it. However, can this, and your other bread recipes, be made with gluten-free flour? I have to be gluten-free.

      this bread can be made with GF flour, since it is a quick bread recipe. My other sourdough recipes that require kneading and rising cannot be made with GF flour.

    I dont keep potato starch or corn starch around. What is the purpose and is there a non-GMO substitute? I use tapioca flour or arrowroot starch to thicken, but is the purpose of potato starch, too? Thanks for your help!

probiotic pickled garlic 🧄 

People always wonder probiotic pickled garlic 🧄 

People always wonder why I add water to my sauerkraut recipes. While the main reason is recipe standardization to account for seasonal and regional variations in cabbage water density, the more simple answer is that extra brine is better than too little!

I especially love love love using extra sauerkraut brine to create more medicinal, probiotic foods. Like this probiotic pickled garlic!

Heirloom culturing, the technique used in this recipe, is my favorite way to use left over fermented vegetable brine. It’s kinda like fridge pickling, but with more microbes.

It’s extra fizzy too, thanks to the high levels of the FODMAP fructan in beet juice. The microbes metabolize the fructans to make the bubbles, so fermented beet juice kombucha is much lower in FODMAPs than plain beet juice!

Sourdough starter makes brownies a little more cake-like, so I had to up the fats in the recipe a bit to keep them moist and used a combo of brown butter and oil.

Fermented garlic honey, and I make mine as an oxym Fermented garlic honey, and I make mine as an oxymel 

🍯✨🫧🧄 the recipe is on my website!
https://cultured.guru

Many historical texts mention the use of both garlic and honey in traditional medicine. Still, none explicitly describe the modern method of combining only these two ingredients and leaving them to ferment. In all my readings on fermentation history, I’ve never come across any historical descriptions of fermented garlic honey, made with only garlic and honey.

However, I did come across many accounts of over 1,200 types of oxymel in Ancient Greece and Persia, many of which include garlic.The ancient Greeks and Persians used oxymels to extract and preserve potent herbs, including garlic. Oxymel is an ancient preparation, and Hippocrates wrote records about its benefits around 400 B.C.E. in On Regimen in Acute Diseases.

The thing to note here is that oxymel uses a combination of honey and raw vinegar.

When we make fermented garlic honey as an oxymel, the pH starts at a safe acidity and remains at a safe acidity (below 4.6). This is because the microbes in raw vinegar (or raw kombucha) ensure the honey is metabolized into more acids. These microbes “eat” sugars similarly to the way they do when making kombucha, wild mead, and vinegar. When we add raw vinegar or raw kombucha to a garlic honey oxymel, we are guaranteeing the presence of many acid-producing microbes that keep the mixture acidic and safe.

PSA: I’m not saying that your garlic honey made without raw vinegar is destined to have botulism. But I am saying without raw vinegar/kombucha it is a concern, and it can happen. I am saying that I’m not comfortable making it without raw vinegar/kombucha. 

I have compiled all my thoughts on garlic honey and botulism in the blog post, linked in my bio! You can also type “cultured.guru” right into your web browser and the recipe blog is on my homepage.
