Sourdough Discard Crackers

It is no secret that professional bakers have to discard a lot of sourdough starters each week. But what many people don’t know is that you can take those discarded bits and turn them into the most delicious crackers ever.

These Sourdough Discard Crackers are easy to make and taste absolutely amazing. Plus, you can customize them with your favorite spices and herbs. So why not give them a try? You won’t be disappointed!

Sourdough discard is the leftover liquid from a sourdough starter. It’s full of wild yeast and other fermentation byproducts that give sourdough bread its characteristic flavor.

Discard can be used to make all sorts of things, including crackers! These sourdough discard crackers are crispy, cheesy, and full of flavor.

What Is Sourdough Discard?

Sourdough discard is the by-product liquid that is left over after you have fed your sourdough starter. The starter is a living culture of yeast and bacteria, and when you feed it, the bacteria multiplies and produces lactic acid, which is the fermenting process.

This increase in acidity gives sourdough bread its characteristic tangy flavor. Sourdough discard can be used in a number of different recipes, including as a leavening agent for bread, as a starter for sourdough pancakes, or even as a substitute for vinegar in salad dressings, making of waffles.  It can also be used as a replacement for buttermilk or yogurt in baking recipes.

While it may seem like a waste product, sourdough discard is actually packed full of flavor and can be a great addition to your baking repertoire. If you have a sourdough starter, don’t throw away the discard – put it to good use in your kitchen!

How To Make Sourdough Discard Crackers: Step By Step Guide

In this tutorial, we’re going to show you how to make sourdough discard crackers step by step.

  • First, you will need some sourdough starter. If you don’t have any sourdough starters available, you can also use bread yeast. Once you have your sourdough starter, you’ll need to mix it with some warm water. Make sure the mixture is about the consistency of pudding.
  • Once the mixture is ready, you have to spread it out on a baking sheet. You will need the crackers to be about 1 inch wide and about 2 inches long.
  • Next, mix together some salt, sugar, and baking powder. You’ll want to mix this together until it’s well combined.
  • When the salt, sugar, and baking powder are mixed together, sprinkle them over the sourdough crackers. Make sure that the crackers are covered in the mixture.
  • Now, let the crackers rise for about an hour. After the hour is up, preheat your oven to 350 degrees Fahrenheit.
  • Once the oven is preheated, you may want to bake the crackers for about 20 to 25 minutes. After the crackers are baked, let them cool off for a few minutes.
  • Finally, you will want to assemble the crackers by putting them together with some butter, salt, and pepper. You can also add some seeds to the crackers if you would like to.

And that’s how you make sourdough discard crackers! Now you can enjoy some of the best-tasting crackers that you’ve ever had.
