Bubbly, fizzy, and just a bit murky, making a wild yeast starter can seem a little daunting, but it's one of the easiest kitchen projects you can undertake. There's only a single step: sealing fruit into a jar filled with water. And then you wait. In less than a week, you have a yeasty starter you can use to bake bread.Fruits, vegetables, and even wild herbs are all sources for wild yeast, but dried fruit is one of the easiest for newcomers to use. Figs, apricots, and raisins work well.
