OK. Please excuse another newbie sourdough question.

I'm following Hamelman's recipe for the Liquid Levain Culture.

I started it on Sunday and it puffed up like crazy after the first feed. It hasn't really done that since then; it just has a bunch of small bubbles on the surface. But it hasn't really risen.

It smells quite good, like sourdough.

Am I doing OK? Should I just keep with the twice-daily feedings for next several days?

Sorry for the newbie questions, but thanks for any help.

Happy baking!
