My first sourdough was a disaster, my first kefir took quite some time before it tasted reasonable (if its ever ‘funky’/too yeasty I use it to make pancakes or muffins), my first fermented veges got thrown out because I didn’t trust them… but I’ve grown in leaps and bounds and have now shown my mum how to ferment veges and make kombucha and I recently spent a week at the snow making sourdough bread and pizza’s for a large group of people – very satisfying!
