If you would like to purchase one (or more) of the starters described in Sourdough Culture you can do so here. The starter will be dried and can be sent via mail anywhere in the world with reliable postal service. (Some starters have had difficulty reaching their destinations in Africa or South America.)
Each starter costs $12.50 and covers the cost of postage inside the U.S. Extra charges may be incurred for mailings outside the U.S.
Payment can be made via PayPal [Eric Pallant]
When you purchase a starter, I’ll place your general address (not your name) on my sourdough map. These starters are already used around the world. Let’s spread the fungal network.
