Sourdough Bread Starter

Sourdough breads need a starter. Starters are variously known as sponge, poolish, or biga in different countries/languages. The concept is the same even if the starters differ in texture. Basically it is a flour and water mix, with optional yeast added, which is allow to ferment for a time before being used to make bread. This is the starter I used for my French Pain de Campagne then for my Italian Ciabatta. I’ve been growing my starter in the fridge consistently since July 2006.

Notes
  1. First you need to kick off the starter. Purists don't add yeast, and instead allow the natural yeast in the flour to develop. I was in a rush, and it was my first sour dough, so I didn't try that.
  2. Replenish the starter when you use any (to get the bulk back up to what you need, or once a week regardless to keep the yeast alive. Always replenish the starter with an equal amount of flour and water. And use enough flour and water to replace the quantity of starter you took out for the recipe. My recipes all use 250 grams of starter, and these are the quantities to replenish. I usually make a loaf each weekend, so I replenish the starter then. The starter will survive a couple of weeks without food, as I discovered when going on holiday.
