Good stuff, as usual.
With regards to sourdough, this is definitely the one thing nobody needs to buy - all you need is organic flour, filtered water, a bit of warmth and five days worth of patience. Afterwards you can dry up a bit of active sourdough in room conditions and store it as a starter for next time to cut the 5 days to 2.
