Whilst it’s fairly easy to make your own sourdough starter (see my favourite recipe here >>) it’s also possible to buy your sourdough starter if you want to start your sourdough bread baking straightaway. Most sourdough bread starters will arrive inactive or dry, to make sure they don’t expand or even explode whilst in transit. For the same reasons, you’ll usually only receive smaller amount. This is absolutely fine as you only need a teaspoon of sourdough starter to start your own. Once you open your new sourdough starter pack, you will need to transfer it to a glass jar or plastic tub and feed with your chosen bread flour to activate it. Every supplier will include step by step instructions on how to look after your starter when you receive it.
