This is a yogurt-based shortcut sourdough starter and it is the easiest entry point for home bakers who have tried and failed with the traditional flour-and-water method. By piggybacking on the live cultures already in yogurt, you skip the uncertain two-week wild-yeast capture and get a stable, usable starter in about five days.
The sequence has two fermentation stages. First, warm milk to 90-100°F (32-38°C), stir in plain unflavored yogurt, and let it incubate in a warm spot for 18-24 hours until it curds up like set yogurt. This is your lactobacillus colony getting established. Then add an equal volume of flour and let it go another two to five days, during which wild yeasts from the flour and air join the party.
The pink liquid warning matters. A clear watery layer on top is normal and gets stirred back in. Any pink or orange discoloration means the wrong bacteria have taken over and the batch is unsafe. Toss it and start again; there is no saving it.
Pro Tips
- Use plain whole-milk yogurt with live active cultures. Greek yogurt works but has lower liquid content, which can slow the first curd stage. Flavored yogurts are full of sugar and off-limits.
- Warm the milk carefully. Above 110°F (43°C) kills the cultures, below 85°F (29°C) slows fermentation to a crawl. A clip-on thermometer is worth ten seconds of hassle.
- Use a glass or stainless steel container, never aluminum or copper. Acidic starter reacts with reactive metals and picks up off flavors.
- Feed the starter with equal parts flour and water every week if you store it in the fridge, or daily at room temperature. A neglected starter goes dormant, then dies.
Variations
- Swap the all-purpose flour for whole wheat or rye flour. Both ferment faster and give a tangier starter with deeper flavor.
- Use kefir instead of yogurt for a more complex microbial starter.
- Once the starter is established, convert it to a fully traditional sourdough by feeding only flour and water from there on. The yogurt cultures fade out over several feeds.
Ingredients
Directions
In a 1-quart pan over medium heat, heat milk to 90 to 100 degrees. Remove from heat and stir in yogurt.
Place in a warm 3 to 6 cup glass, ceramic, plastic or stainless steel container with a tight lid.
Cover and let stand in a warm place until mixture is the consistency of yogurt and a curd has formed. (You can test the mixture by tilting the container. If the mixture doesn’t flow freely when the container is tilted, it’s ready.)
The curding process takes about 18 to 24 hours. You’ll need to check it periodically.
If some clear liquid rises to the top of the milk, stir it back in.
NOTE: If the liquid turns pink, discard the batch and start again.
Once the curd has formed, add the flour and stir until smooth.
Cover again and let stand in a warm place until the mixture is full of bubbles and has a good sour smell.
This should take about 2 to 5 days. Again, if some clear liquid rises to the top stir it back in.
If the liquid turns pink, discard the batch and start again. When the mixture is ready, you can keep it covered and store it in the refrigerator until you need it.
The recipe makes about 1⅓ cup starter.
