Check out this video to learn how to mix your flour and water to the perfect consistency and start your starter! Step 1: Start Your Sourdough Starter - Use whole rye flour and warm water (30-35°C / 86-95°F). - Measure 100 g flour and start with 100 g water (add more if too thick). Aim for hummus-like consistency. - Mix well - no dry flour. Add water slowly (10-15 g at a time) if needed. You can go up to 150g of water total (along with the first 100g you've added). - Check the mix temperature (should be 26-30°C / 79-86°F). - Put it in a large jar, lid slightly open. Mark the level with a rubber band. - Keep it warm (26-30°C). - Wait up to 48 hours - look for bubbles, rise, and a peak before moving to step 2. The mixture should also fall down from its peak before you can move on to Step 2.
