Instructions for rehydrating a dried sourdough starter that will work whether you're using sourdough starter you've dried yourself, been gifted by a friend or purchased.
300gFlour of your choice (enough for around 6 feeds of 50g)
300gWarm Water (enough for around 6 feeds of 50g)
Instructions
DAY 1 - MORNINGStarting with a clean jar, add 10g of dried sourdough starter. Add 50g of warm water and stir it together until the starter is completely covered and coated by the water. Now add 50g of flour and stir in well.Cover and leave for approximately 24 hours.
DAY 2 - MORNINGDiscard all but 50g of your starter (you could just place 50g of the starter into a clean jar and get rid of the rest). Add 50g of water and 50g of flour to your mixture. Give it a really good stir.Cover and leave for approximately 12 hours.
DAY 2 - EVENINGAfter 12 hours, discard all but 50g of your starter (you could just place 50g of the starter into a clean jar and get rid of the rest). Add 50g of water and 50g of flour to your mixture. Give it a really good stir.Cover and leave for approximately 12 hours.
DAY 3 - MORNINGDiscard all but 50g of your starter (you could just place 50g of the starter into a clean jar and get rid of the rest). Add 50g of water and 50g of flour to your mixture.Give it a really good stir.You'll need to repeat step 3 above every 12 hours for around 3-7 days. You want your starter to become bubbly and consistently doubling after each feed.
Notes
Depending on the type of flour you use, the initial mixture will seem quite dry - don't worry it will thin out as the starter begins to activate. If you're really worried, spray a little water onto the top of the mixture.
