By this point in quarantine you’re either pumping out beautiful loaves of sourdough bread weekly, or looking at the rest of us sourdough freaks like we are nuts.

Summer is on the way and the rising temps start to make me second guess cranking the oven up to 500 degrees for an extended period of time.

I don’t want my sourdough starter to perish though. Me and ol’ Frankenstein have been through so much the past 9 months.

During the past 2 months I have come to learn and argue with my husband over his snacking tendencies. The man looooves his Cheez-It’s. Even if he is stealing them right out of his kids’ snack bowls.

Did you not see the top of the fridge? It is literally covered in cereals and salty snacks!

A box of cheese crackers goes in a week or less in our household. these boys are addicted.

I knew the kids wouldn’t dare touch these crackers. There was no way that I could convince them that, despite the way they look, they taste exactly like their favorite cheese cracker.

Just a little pause and a PSA about cheese crackers. If you aren’t into the crazy world of wild fermenting and sourdough, I do have several similar cracker recipes that are just as good that do not use any part of sourdough.

Try these if you are in the mood for some homemade crackers:

Last but not least, my kids favorites!

All of the above crackers are very similar in the crispy, airy, cheesy crunch factor as these sourdough crackers.

Sourdough discard crackers are made very simply. Combine a cup of the starter discard with olive oil, and your choice of cheese. Mix it up and then spread it flat on a baking sheet. Sprinkle some salt on top. Bake until crisp and then either cut or break into rustic cracker pieces.

I really like a good sharp cheddar topped with either Maldon Sea Salt or Everything But the Bagel Sesame Seasoning Blend. I have also made these with Monterrey Jack cheese.

The trick is to finely shred the cheese yourself.


The pre-shredded stuff has a coating on it that messes with the melty/cooking factor. Trust me, I am into food (especially cheese) for a living.
