Sourdough starter
HB-2137 · Hand-built original
The sourdough starter is a fermented dough in which bacteria and lactic ferments develop, favoring natural leavening.
Main ingredient: ¾ oz raisins
Ingredients
- 1¾ oz raisins
- 3½ oz strong Manitoba flour, for day 1
- 1¾ oz type 0 flour, for day 1
- 8 Tbsp water at room temperature, for day 1
- 5 Tbsp water, for the refreshments
- 3½ oz strong Manitoba flour, for each refreshment
- 1¾ oz type 0 flour, for each refreshment
- 2 1/2 tbsp sugar, for soaking the raisins
- about 1 qt water, for soaking the raisins
- type 00 flour, for dusting
Method
- Day 1: soak the raisins in the 1 qt of water with the sugar for at least 2 hours, then squeeze them well and reserve 8 Tbsp of the soaking liquid — it carries the wild yeasts that start the culture. Discard the raisins.
- Mix the 3½ oz Manitoba flour and 1¾ oz type 0 flour with the 8 Tbsp raisin water to a thick, lump-free batter in a clean glass jar. Cover loosely with cloth or a loose lid and leave at warm room temperature (about 75-79°F) for 48 hours, until bubbles appear.
- First refreshment: take 5¼ oz of the starter, discard the rest, and mix it with 3½ oz Manitoba flour, 1¾ oz type 0 flour and 5 Tbsp water. Cover and leave for 24 hours.
- Repeat the refreshment once a day for the next 5-6 days, always keeping the same proportions. The starter is ready when it doubles in size within 4-6 hours of a feed, smells pleasantly tangy rather than sharp, and a spoonful floats in water.
- Once active, keep the starter in the fridge and refresh it once a week with the same flour and water proportions. Bring it to room temperature and give it one or two feeds before using it for baking.
- Use the starter at its peak, a few hours after a feed when it has doubled and is full of bubbles.
