Gluten-Free Sourdough Discard Cornbread

Key takeaway

A preheated skillet fries the cornbread edge; certified gluten-free cornmeal is non-negotiable in a celiac kitchen.

Certified gluten-free cornmeal, 120g discard, and a screaming-hot skillet. Southern-leaning, not cake-sweet.

The short answer

Cornbread should crunch at the edge. Preheat a 10-inch skillet with 15g oil or bacon drippings. Batter: 140g certified GF cornmeal, 80g 1:1 flour, 120g discard, 180g buttermilk or plant milk plus 10g lemon, 1 egg, 30g oil, 15g sugar, 8g baking powder, 3g soda, 5g salt. Pour into the hot skillet, bake 400F 18–22 minutes. Use certified gluten-free cornmeal—corn is often contaminated. This is chili bread, not dessert.

For the method behind gluten-free structure, read the gluten-free sourdough guide and keep a lively culture with the starter guide.

Why it works

  • Hot fat is the crust.
  • Discard plus buttermilk is a lot of acid—soda is required.

Instructions

  1. 1

    Heat oven to 400F. Put 15g oil in a 10-inch skillet and preheat 10 minutes.

  2. 2

    Whisk dry ingredients.

  3. 3

    Whisk discard, milk, egg, and remaining oil.

  4. 4

    Combine. Pour into the hot skillet—it should sizzle.

    Bake 18–22 minutes until gold and pulling from the edges.

  6. 6

    Cool 10 minutes. Cut wedges.

  7. 7

    If it tastes gritty, your cornmeal was too coarse or you skipped the rest—let batter sit 5 minutes next time.

FAQ

Can I use active starter instead of discard in this cornbread?

Yes. Fed starter is milder and puffier. Reduce any baking soda slightly if the batter already tastes very tangy.

How much flour and water is in 100g of discard?

A 100% hydration starter is about 50g flour and 50g water. Reduce those amounts from the rest of the formula so the bake is not gummy.

Is discard safe to eat uncooked?

Treat it like other raw flour batters. Bake or cook it through. Fridge discard should smell pleasantly sour, not rotten.

My discard is very thin.

Stir it, then weigh. If it is far wetter than 100% hydration, use a little less water in the recipe.

How old can discard be?

We use discard within two weeks in the fridge. If it has mold, pink streaks, or a rotten smell, compost it.

Technique

Keep the method close

Psyllium, fermentation temperature, and a celiac-safe starter matter as much as the formula.
