I've been baking bread every weekend, or two, for over a year now. Currently in Helsinki my local shops have run out of flour, and dried yeast, but I'm still good for now, as I have a surplus of flour and I started making my own sourdough starter. Sourdough starters are pretty easy to create, but I usually make one then go back to dried yeast after a few months. I suspect the batch I'm using at the moment will last longer than most: https://www.instagram.com/p/B-R-kkphHPP/ https://www.instagram.com/p/B-R-kkphHPP/
