If you maintain a sourdough starter, these tangerine muffins are a great way to use up some of the extra discard when you feed your levain. 

The flavors of the tangerine along with the sourdough adds a bit of tang to these sweet and citrus-y muffins.

Don't worry. If you don't have a sourdough starter, you can substitute an extra 100 grams of flour and 100 grams of water. However, if you do maintain a starter, these muffins will help assuage any guilt you may have in tossing out extra starter. 

If you're not familiar with maintaining a sourdough starter, here's how it works...

Maintaining a sourdough starter: 

Once you have a viable sourdough starter, to maintain it, you have to pull out a small amount of your starter to use in a bread recipe and then feed it with flour and water so that it grows and gets active. Once it's active, you use it to leaven your bread. 

The problem is that sometimes you end up with a lot more starter than you can use, so you often have to toss some of it.. or end up with a huge amount of sourdough starter... like "the blob." 

I keep my starter in the refrigerator, so I have to revive it when I'm ready to use it. This requires a couple of "feedings" of a 50/50 mix of flour and water (by weight) to get the starter active. While this method is super convenient, it can produce more starter than I want, and I still toss some of the excess starter periodically. 

As much as I can, I use the excess for sourdough onion rings, sourdough cranberry muffins, blueberry cornmeal muffins, sourdough pecan muffins, and these tangerine muffins. Plus, you can use the discard for cheesy crackers, chocolate chip cookies, and Belgian-style waffles

If you totally dislike tossing out excess sourdough, just remember you can replace flour and water in any recipe with some of your sourdough starter. All you need is a kitchen scale and a calculator. 

Ingredients You Will Need:

Sourdough Starter: You can use freshly fed or even starter that is totally spent. 

Pantry and Fridge Ingredients: All purpose flour, sugar, baking powder, eggs, baking soda, salt, pure vanilla extract, and grapeseed or vegetable oil. 

Tangerines: You will need the zest of two tangerines plus 2 tablespoons of juice. I also uses an optional ingredient, orange oil

The Muffin Method:

Use the "muffin method" to make these muffing. What is the muffin method? 

Combine the dry ingredients in one bowl and the wet ingredients in another bowl. Next, pour the dry ingredients into the wet ingredients (or vice versa) and gently stir everything together. 

Next, using a cookie scoop, drop the batter into paper lined cavities of a muffin tin and bake for 15 to 18 minutes. 

Once the muffins cool, mix some tangerine juice with powdered sugar and drizzle the tops of the muffins with it.

These muffins are great the day they are made. You can also keep them for up to three days in an air tight container at room temperature. 

Before glazing, you can individually wrap each and freeze them as well. After thawing, drizzle them with the glaze. 

If you don't have tangerines, you can substitute any citrus, including lime, lemon, orange, or grapefruit. These muffins aren't too sugary, so there is no reason to adjust it, although you can if you want to.

  1. My poor sourdough is shoved somewhere into the back of my refrigerator. I need to pull it out and show it some love and attention.

  2. I think the main reason I maintain a starter is for muffins and pizza dough. These look lovely!

  3. Lovely muffins, as usual, Karen! And now I'm on a hunt to see where to buy orange oil. (Oh, just noticed you shared a link! Thank you!)

  4. It is well past time I get the starter I brought back from Alaska going! Glad I've got some tangerine juice stashed in the freezer. And sourdough onion rings? Heading to check those out too!
