Tenuous link you may think, but when I started reading up on sourdough, and wild yeasts, starters, fermentation etc. it all seemed very familiar. It's basically the lambic of the bread world.
Plus there wasn't food section, so forgive me if this is in the wrong forum.
I started to make a starter for a French rustic bread on Saturday. Basically you make a small amount of dough from wholemeal flour and water. Cover and keep warm for a couple of days. Scoop out the moist inside, dispose of the rest, add more flour and water, and keep for a couple of more days.
I'm at the stage now where I should see something happening (the dough should rise), but there's defenitely some fermenting smells coming from it.
After that, you build it up with more flour and water, set some aside for the starter for your next loaf, and make bread from the dough.
There's a good link here[/url:1p3tss09] about making San Francisco sourdough. I hope to try this one next week. They seem to make the starter the consistency of a batter, as opposed to the French recipe I'm making now. Once you have this starter, like beer yeast, it can be kept in the fridge for a month. Feeding it with more flour and water will prolong the life.
If anyone is interested in cooking you might like to give it a go.
