Thin, crisp, classic saltine-style crackers made from sourdough discard. No yeast, no added water, and rolled ultra-thin using a pasta roller. This recipe is optimized for repeatability with a pasta roller; hand-rolling works as long as the dough is rolled very thin.
In a bowl, mix sourdough discard, melted butter, salt, sugar, flour, and optional seasoning until a smooth, cohesive dough forms.
No additional water is needed.
Divide dough into 3 pieces, about 140 g each.
Flatten each piece into a rectangle.
Roll through a pasta roller, starting at the widest setting and progressing gradually to level 7.
(Optional: fold the dough in thirds once at a lower setting for extra even sheets.)
Hand-Rolling Note
Hand-rolling works fine as long as the dough is rolled very thin. If it resists or shrinks back, rest 5–10 minutes and continue.
Transfer dough sheets to parchment-lined baking pans.
Cut into squares and dock with a fork to prevent bubbling.
Lightly mist or brush with water and sprinkle with flaky or kosher salt.
Bake at 350°F for 20 minutes, rotating once, until lightly golden and dry.
Cool completely on the pan. Crackers will crisp fully as they cool.
