Sourdough starter tips

Most people kill their sourdough starter with kindness. They feed it daily, keep it warm, panic when it separates. The starter doesn't need your anxiety. It needs neglect at the right moments and attention when it counts. King Arthur Baking gets this. Their method works because it respects what wild yeast actually does in the world, which is survive without you.

The flour matters more than the schedule. Bread bakers who switch between all-purpose and whole wheat see the difference immediately. Whole wheat feeds the microbes better. Rye flour works faster than both. Your starter will double in four hours instead of eight. The container matters too. Glass shows you what's happening. Plastic holds smells. Metal can react with the acid. Professional bakers use wide-mouth mason jars for a reason.

Temperature controls everything else. Seventy-five degrees is the sweet spot. Warmer and the bacteria take over, making it too sour. Cooler and nothing happens for days. You can slow it down in the refrigerator for weeks. You can speed it up on top of the water heater. The smell tells you when it's ready. Sweet and yeasty means go. Vinegar sharp means it's hungry. Nail polish remover means start over. Sourdough communities argue about ratios and timing, but they all agree on the nose test.

The real secret is the discard. Most people throw it away or make pancakes. Smart bakers keep a discard jar in the fridge and use it for pizza dough, crackers, even chocolate cake. The tang adds complexity without the wait. Your starter becomes a pantry staple instead of a project. Feed the mother, use the children. The rhythm becomes automatic.
