I originally saw this on Twitter on August 4 and again a few days later and found this link.
If you have a twitter account, you can do a search for Seamus Blackley and follow dozens of tweets about his "adventures in yeast, dough and breads" - not something you would usually see from a PHYSICIST! He shows where he is milling with emmer. and then the various breads. It's a very interesting thread.
and I saved the link to The Guardian article: and the BBC article
And I tweeted about the National Geographic production when Ed Wood helped reconstruct an ancient Egyptian bakery back in 1993. (they were excavated in 1991) That set Ed on a search for other strains of wild yeasts which became the Sourdo.Com selections of various cultures from around the world.
I have posted in much earlier threads about my adventures with some of these strains, back when I was doing a lot more baking.
P.S. There is also on Twitter - an Ancient Yeast Club!
