In the last post, I experimented with the amount of sourdough starter, and the effect that it had on the final taste and texture of the loaf. This time around, I decided to completely overhaul my usual method for sourdough, and try something new – a firm starter.
Usually, I use between 20 – 40% of starter, made from a 1:1 mix of rye flour and water (for an explanation of the %, see my previous post on baker’s percentages). I find that this “100% hydration” starter give reliable results, but, as I’m always interested in finding out new methods, I decided to give the firm starter method a try.
The process began by converting my usual starter to a white flour starter – basically, feeding it with white instead of rye flour. The initial mix was actually wetter than I usually use: 130g of water to 100g of flour, making a foamy and light batter. This, as explained below, was finally built up into a firm dough, briefly kneaded, and then left overnight before beginning the bread.
The bread itself rose very well (for one loaf, it rose too well, leading to an unsuccessful loaf that I will be writing about later!) and, after retarding overnight in the refrigerator, baked into a great looking loaf with a golden crust and light, open crumb.
Wholegrain and millet sourdough – makes 3 small loaves
- 250g white plain (all-purpose) flour
- 450g white starter at 130% hydration
- 650g firm starter
- 200g wholegrain flour
- 50g millet meal
- 450g white plain (all-purpose) flour
- 19g salt
- 420g water at room temperature
- This recipe takes a few days to plan ahead – I refreshed my starter with white flour on Wednesday, built it up to about 250g on Thursday, and made the firm starter on Friday. Mix the wet starter and flour together, and knead for several minutes to combine. Refrigerate the starter, covered, overnight.
- Cut the firm starter into pieces, and add the remaining ingredients. Knead for 10-15 minutes. Place into a bowl and bulk ferment for 4 hours.
- Divide and shape the dough into 3 small boules (at this stage, I shaped into one small and one large loaf – the large loaf, it turned out, was a bad idea…). Place boules into floured bannetons. Proof for 3 hours at room temperature, then refrigerate, well covered overnight.
- On the morning of baking, take the first loaf out of the fridge and preheat the oven to maximum with a lidded cast iron pot (“Dutch oven”) on the middle shelf. Bake the first loaf for 30 minutes with the lid on, and 15 with the lid off. Repeat with the remaining loaves, removing each from the fridge whilst one is baking.
- Cool on a wire rack for at least an hour.
Throughout this post I’ve mentioned a loaf that didn’t quite work. For reasons I’ll explain in a later post, the large loaf that is in some of the pictures did not come out very well – the interior was fine, but the exterior was pale and not very well crisped up. Trying out new methods sometimes gives disappointing results, but the small loaf came out very well!
