How to make a sourdough starter

 If you love sourdough bread, you might want to try making your own sourdough starter from scratch. A sourdough starter is a mixture of flour and water that has been fermented by wild yeast and bacteria. It gives sourdough bread its distinctive tangy flavor and airy texture.

Making a sourdough starter takes about a week, but it's not difficult. You just need to feed it regularly with more flour and water to keep it alive and active. Here are the basic steps to make a sourdough starter:

Day 1: Mix 50 grams of whole wheat or rye flour with 50 grams of cool water in a clean glass jar. Stir well, cover loosely, and let it sit at room temperature (about 70°F) for 24 hours.

Day 2: You may not see much activity yet, but don't worry. Discard half of the starter (about 50 grams) and add 50 grams of all-purpose flour and 50 grams of cool or lukewarm water to the remaining starter. Stir well, cover loosely, and let it sit at room temperature for another 24 hours.

Day 3: By now, you should see some bubbles and a pleasant fruity smell. This means the wild yeast and bacteria are starting to grow. Discard half of the starter (about 75 grams) and add 75 grams of all-purpose flour and 75 grams of cool or lukewarm water to the remaining starter. Stir well, cover loosely, and let it sit at room temperature for another 24 hours.

Day 4: The starter should be more active now, with more bubbles and a stronger smell. Repeat the same feeding process as day 3, discarding half of the starter (about 100 grams) and adding 100 grams of all-purpose flour and 100 grams of cool or lukewarm water to the remaining starter. Stir well, cover loosely, and let it sit at room temperature for another 24 hours.

Day 5: The starter should be very active now, with a lot of bubbles and a tangy smell. It should also double in size after each feeding. Repeat the same feeding process as day 4, discarding half of the starter (about 125 grams) and adding 125 grams of all-purpose flour and 125 grams of cool or lukewarm water to the remaining starter. Stir well, cover loosely, and let it sit at room temperature for another 24 hours.

Day 6: The starter is almost ready to use now. You can test its readiness by dropping a spoonful of it into a glass of water. If it floats, it's ready. If it sinks, it needs one more feeding. Repeat the same feeding process as day 5, discarding half of the starter (about 150 grams) and adding 150 grams of all-purpose flour and 150 grams of cool or lukewarm water to the remaining starter. Stir well, cover loosely, and let it sit at room temperature for another 24 hours.

Day 7: Your sourdough starter is ready to use! You can use it to make sourdough bread or store it in the fridge for later use. To keep it healthy, you need to feed it once a week by discarding half of it and adding equal amounts of flour and water to the remaining starter.
