I need to "pay it forward" from the person who sent me some. Why don't you PM me your address and I will send it, provided you are in the USA ?
One thing I should mention, it has been said that Patsy's doesn't actually use a sourdough starter. Whatever it is, it is very active. And likely to have been taken over or combined with local yeasts at this point anyway from feeding and leaving out on the counter.
But, the stuff I have is freeze dried from the original person who sent it to me, so whatever I have been doing with my starter will have no effect on what I send to you.
