In a medium bowl, combine the sourdough discard, melted butter, and salt. Stir until the mixture is smooth and well-combined. The batter will be pourable but thick enough to hold its shape.

Preheat your oven to 350 F. Line a baking sheet with parchment paper, or a silicone mat. Pour the sourdough mixture on the baking sheet and use a flat spatula to spread it to each corner, you want the mixture to be very thin and almost see through

Bake the crackers for 10 minutes, remove them from the oven and use a pizza cutter to slice them into bite size pieces. Place them back in the oven and bake for 15-20 minutes, or until they are golden and crispy.

Sprinkle the crackers with flaky sea salt, or herbs of your liking. Enjoy them warm, brushed with a little extra melted butter if you’re feeling indulgent.
