In case there is any confusion about traces of beef in King Arthur's
sourdough starters, I asked KA's customer service to clarify. The
response follows:
>Thank you for your email. Item # 1040 the La-4 French Sourdough
>Starter does contain traces of beef. This is a dry starter that
>comes in 5g packet that is enough starter for about 12 loaves of
>bread. Item #1522 our fresh sourdough starter does not contain
>traces of beef. This starter is the fresh sourdough starter that
>you have to feed about once a week. Please let us know if we can be
>of any further assistance. Happy baking!
