Sourdough Discard Crackers

We consider these “sourdough discard” crackers because you use sourdough starter in the recipe, but we don’t use it for rising, and it is not necessary for the baking process. So the starter is considered “discarded” into the sourdough crackers recipe.

I use a stirred-down active, bubbly sourdough starter in these crackers. The starter adds such delicious flavor to these crackers, though.

It may not contribute to baking, but it gives the best tangy flavor. Jon and I think these crackers taste like high-class goldfish.

Sourdough Starter Crackers

You have options with these crackers. First, you can mix the dough, refrigerate the dough for an hour covered, then bake.

Alternatively, let the dough ferment in the fridge for 24-48 hours before rolling, cutting, and baking the crackers. A longer ferment can make these easier to digest, especially if you have sensitivities to non-sourdough gluten products.

Sourdough Crackers Recipe

This is such a simple recipe for sourdough crackers, and it’s best to weigh all your ingredients for the best crispiest texture. If rosemary isn’t your thing, here are some fun alternative mix-ins to try:

  • Parmesan cheese
  • Garlic and black pepper
  • Sesame seeds
  • Minced Jalapeno and shredded cheddar

How to Make Sourdough Crackers

You are probably wondering how to make crackers by now. First, you mix the dough. Next, you wrap the dough with reusable bees wrap or plastic wrap and refrigerate it.

Then all that is left is to roll, cut, and bake the crackers. When cutting the crackers, you need to poke them with a fork to ensure they don’t puff up in the oven.

These are butter crackers, so once they are baked and cooled, you should store them in an airtight container at room temperature, so they don’t stale. I keep mine in a big sealed weck jar.

Buttery Rosemary Sea Salt Sourdough Crackers

These are the most buttery, flavorful, crisp sourdough crackers you will ever have! Once you try these crackers, you’ll never want to do anything else with your sourdough starter discard. Enjoy these crunchy, flaky crackers with cheese and fruit for a perfect snack.

  • Prep: 10 minutes
  • Cook: 25 minutes
  • Total Time: 24 hours 35 minutes

Ingredients

  • 200 grams sourdough starter, stirred down
  • 120 grams all purpose flour
  • 5 grams sea salt
  • 4 tablespoons unsalted butter, room temperature
  • 2 tablespoons fresh rosemary chopped, plus extra set aside
  • Olive oil, for brushing
  • Flake salt

Instructions

  1. Mix the sourdough starter, flour, salt, butter, and rosemary. Knead until a smooth dough forms.
  2. Shape the dough into a small slab. Wrap tightly with reusable bee’s wrap or plastic wrap.
  3. To bake immediately, refrigerate for 1 hour. For a longer ferment, refrigerate for 24 hours, then proceed to the next step.
  4. Preheat the oven to 350°F.
  5. Lightly flour a piece of parchment paper sized to fit your baking pan and the top of the dough. (You may want to split the dough and work in batches. I had to use two sheet pans to fit all the crackers)
  6. Place the dough onto the floured parchment and roll it about 1/16 inch thick.
  7. Transfer the dough and parchment together onto a baking sheet.
  8. Cut the dough into about 1-inch squares; I suggest using a pizza or cracker cutter.
  9. Poke each cracker a few times with a fork; this will keep them from puffing up.
  10. Lightly brush with extra virgin olive oil and then sprinkle the salt over the top of the crackers.
  11. Bake the crackers for 20 to 25 minutes until they start to crisp and brown around the edges. Midway through, rotate the baking sheets.
  12. When browned and crisped to your liking, remove the crackers from the oven and allow them to cool.
  13. Store crackers in an air-tight container at room temperature for about a week or two. I like to store them in a sealed glass weck jar.

      Maybe, but I’ve never made them with GF flour and a GF starter so I’m not sure.

      If you don’t need them 100% GF, I’ve used my normal starter/discard and almond flour. No gut issues thanks to the 24hr fermentation.

    These crackers were so good!! My mother-in-law took most of them home with her when I made them because she loved them so much! The tanginess from the starter is awesome and I imagine you could pretty much change up the flavor to whatever you want!

    Nom nom nom. I’m still looking for the optimal thickness and the baking time with my not-so-consistent oven but darn these crackers are delicious. Even if they get a bit darker from the edges or stay softer. Nom.

      no, it needs to be a fat that is pretty much solid at room temperature. coconut oil could work.

    Fantastic taste and easy to make! I love Simple Mills rosemary sea salt crackers and was looking for something that would allow me to replicate them. This is the recipe! I decided to make an AP batch and an almond flour batch. Needed to add more flour to the almond batch, but both turned out great.

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.

Oxymel is a medicinal herbal elixir, made through Oxymel is a medicinal herbal elixir, made through the fermentation of herbs in honey and raw vinegar. 

It’s my favorite time-tested herbal remedy that’s over 2,400 years old. It originated in ancient Greece and Persia, where it was considered a gift from the gods.

Hippocrates, the famous ancient Greek physician, was a staunch advocate of oxymel and incorporated it into his medical practices. Depending on the herbs used to make it, oxymel can help with many ailments and improve health in various ways!

In a world where everyone is asking AI, I set out to learn about the best herbal combinations from real, practiced experts in herbalism.

I felt so much joy collaborating with these herbalists @openspace.center @karlytheherbalist @lilianaruizhealy and @the.brettivy to recommend the best medicinal herb combinations in this recipe!
