Use these instructions to maintain your fresh sourdough starter or activate your new dry sourdough starter.
Step 1: Lightly stir the starter.
Step 2: Put 25g of the starter (a tablespoon) into a jug or sterile jar. Discard the rest.
Step 3: Add to this 100g of water (use warm water at 35 °C). Mix well.
Step 4: Stir in 100g of Strong White Bread Flour. Again, mix well.
Step 5: Leave the jar in a cool place until the mix has doubled in size (usually 6-8 hours).
Step 6: Always remake the starter in a clean, sterile jar. Keep it covered, but not airtight
Step 7: You should refresh your starter at least once a week
