I’ve just about managed to get a new sourdough starter to bubbling good health, and have been amazed by how simple the process is.
All you need is water, flour, and time (as well as the ability to handle that day-three stench).
But just because it can be that easy, it doesn’t mean it always is. For instance, Paul Hollywood grates an organic Cox apple into his – and he’s not the only expert to recommend the method.
Here’s why that’s a great (or should I say... grate? Sorry!) idea.
Why should I grate an apple into my sourdough starter?
Of course, the step is completely optional. But given that sourdough starters are used for their wild yeasts and “good” bacteria, the addition makes sense.
