How to ship Sourdough Starter cross country?
In 2 weeks I'm moving from San Francisco to the east coast. I'm flying out there and wanted to know if there was any way of shipping my sourdough starter without airport security thinking I"m carrying plastic explosives in my checked luggage. I've heard of drying it out on silpats and transporting it as a fine powder, but I'm afraid that would also cause problems. Would you simply FedEx overnight the package? Any suggestions are greatly appreciated.
