Gluten-free sourdough bread

I was impressed by the visual on YouTube. I hope this works out for me too. As it sits, the recipe is basically a 1lb loaf (boule, bâtard, etc.).

Ingredients

390 g gluten-free bread flour*
60 g gluten-free sourdough starter**
5 g psyllium husks (or 1½ tsp psyllium husk powder)
6 g kosher salt
10 g baking powder (heat-activated variety)
390 g water
26 g olive oil
21 g honey

Preparation

1. Feed starter with 30-50 g whole-grain flour* and 30-50 g water. Leave to double.

2. Mix bread ingredients using dough hook.

3. Cover dough and allow to proof until puffed (but not doubled in size), 3-4 hours. Cold-proof overnight.

4. Turn dough out on a floured surface. Add ¼-½ tsp backing soda. Knead until smooth adding flour if necessary.

5. Shape the dough into a bâtard and turn over into a floured banneton. Proof for 2-6 hours.

6. Preheat a Dutch oven to 450°. Place the dough on parchment paper and score it. Put the pâton into the Dutch oven and bake for 40 minutes at 450°. Remove lid and continue baking for another 20 minutes.

Gluten-free flours (FYI)

Gluten-free bread flour blend*

See recipe here.

285 g potato starch
250 g super fine white rice flour
75 g tapioca starch
75 g whey protein isolate
15 g xanthan gum

Gluten-free sourdough starter**

See recipe here.

50 g brown rice flour
60 g water

- If thicker than pancake batter, thin with 10 more grams of water.

- Stir to combine, leave in jar partially covered for 24 hours, then feed with 30 g flour and 40 g water. Repeat three more days. This is pretty much the same way as making a gluten-laden sourdough starter.

- On day 5, discard ½ the starter and refeed.

- Day 6, don't discard ½ the starter and refeed.

- Day 7, discard ½ the starter and refeed.

- Day 8, don't discard ½ the starter and refeed.

- Day 9, discard ½ the starter and refeed.

- Day 10, look for bubbles and odor. If not, keep cycling feed.

- Store as normal sourdough feeder.
