Olive Oil Sourdough Discard Crackers

Written by About Olive Oil | May 2, 2020

Here is an easy recipe for homemade crackers that features sourdough starter discard and extra virgin olive oil. This recipe can be modified for different flavors and tastes and cuts down on waste.

Is it just me, or is everyone suddenly making sourdough bread? I recently received some sourdough starter from my sister and have turned out a couple of decent boules. But I have to admit, my favorite part is feeding the starter. I'm not alone. Many of my friends have even given their starters names. I haven't gotten that far but I am rather attached to my starter and hate discarding any of it. 

Sourdough starter is made from wild yeast in the air around us and in the flour that we feed it. Every few days, you need to feed your sourdough starter. King Arthur flour recommends putting 4 ounces starter in a container and adding 4 ounces by weight of flour (around 1 cup) and 4 ounces of water. The starter that is leftover from the previous batch is called discard and you are supposed to throw it away! 

If you are anything like me, you just can't throw away food, especially now when flour is so hard to obtain. The good news is that you can use this recipe to create delicious crackers that your whole family will love. Unlike other recipes, this recipe does not call for additional flour, rolling pins or scoring and cutting. 

The total time to prepare this recipe is 2 minutes plus 1 hour for baking.

Ingredients:

  • 1 cup sourdough discard (220g or 7.76 oz)

The basic recipe above can be modified in so many exciting ways such as adding herbs, cheese and spices. Its also delicious spread with cheese or smashed avocado.
