Sourdough discard tortillas

Sourdough discard tortillas turn unfed starter into soft, foldable flour tortillas with no yeast and no long proof. Mix 200 g discard with 250 g flour, oil, and salt, rest the dough, then roll thin and griddle each round on a hot dry skillet for under a minute a side. The discard does double duty here: it adds flour and water to the dough and lends a faint tang that store-bought tortillas never have. Total time is about 20 minutes of work plus a rest, and you get eight tortillas that fold without cracking.

This is one of the best homes for the starter you would otherwise tip down the drain. Cold discard straight from the fridge works fine, and it does not need to be active or bubbly. For more ways to clear the jar, see the discard recipes hub.

Ingredients

Weigh in grams for consistent dough. Discard hydration varies, so treat the water as a slider, not a fixed amount.

• 200 g sourdough discard (100% hydration, equal flour and water by weight)
• 250 g all-purpose flour, plus more for dusting
• 40 g olive oil or melted lard
• 5 g fine salt
• 40 g warm water, added as needed

The fat is what keeps these pliable instead of stiff. Lard gives the most traditional, tender result, but olive oil works well and keeps them plant-based. If your discard is on the wet side, you may need none of the extra water. If it is stiff, you may need all of it.

Method

1. Combine the discard, flour, oil, and salt in a bowl. Stir until shaggy, then add warm water a little at a time until the dough comes together. It should be soft but not sticky.
2. Knead for 4-5 minutes until smooth and slightly tacky. Cover and rest 30 minutes to an hour at room temperature. This relaxes the gluten so the rounds roll thin without snapping back.
3. Divide the dough into 8 equal pieces, around 65 g each. Roll each into a ball, cover, and rest 15 minutes. Skipping this rest is the main reason tortillas shrink while you roll.
4. On a lightly floured surface, roll each ball into a thin round, about 18-20 cm (7-8 in) across. Aim for an even thickness so they cook evenly.
5. Heat a dry skillet, cast iron pan, or comal over medium-high, roughly 230C (450F). Lay a tortilla down and cook 45-60 seconds, until brown spots appear and bubbles rise.
6. Flip and cook the second side 30-45 seconds. A good puff means the inside is steaming and staying soft. Move to a stack under a clean towel.

Timings are estimates. Pans and stoves run hot or cool, so judge by the brown spots and the puff rather than the clock. The first tortilla is your test for heat: if it scorches before it puffs, drop the temperature a notch.

Tips

• Rest twice. The dough rest and the ball rest both matter. Together they make the difference between rounds that roll easily and rounds that fight you.
• Roll thin. Thicker tortillas turn out bready. If yours feel heavy, roll thinner.
• Keep them soft. Steaming the stack under a towel traps moisture and keeps the edges from drying and cracking.
• Tang control. Older discard tastes more sour. For a milder flavor, use discard a day or two old, the kind you set aside when feeding a starter.

Storage

Cooled tortillas keep three to four days in a sealed bag at room temperature, or freeze them with parchment between each for up to two months. Reheat on a dry pan for 20-30 seconds a side. Skip the microwave alone, which tends to make them rubbery.
