San Francisco sourdough starter and Carl's starter
A friend on another ng recommended I post here with my query about
sourdough starter and Carl's starter. Three or four years ago, a poster
from uk.food+drink.misc sent me some San Francisco starter and also
mentioned 'Carl's starter'. Gradually, the starter changed and became
'London starter'. Can anyone please tell me where I can obtain San
Francisco starter? Many thanks in advance.
