Lovely stuff

Took about 7 days of feeding to really perk up, but now well established. It was winter time and it really did benefit from warmer rooms. Now using it in just about every baked good we make.

San Fran sour dough

This is my third go with the San Francisco sour dough starter. First try live it was fantastic, second was the freeze dry this didn’t work at all third is live and is proving to be difficult it’s no way as lively as the first was followed tha instructions to the letter but does not seem to be rising very much, and when I make the bread up and store it for 24 hrs in the fridge it doesn’t. Seam to rise much there ether. But the bread turned out quite nice. Not sure if why it’s not the same as my first batch .
