Hello all, my 4 week old starter is rising nicely, well over doubling, quite puffy but has virtually no bubbles, just a few large ones on the surface. It's passing the float test. There are no posts about a non-bubbling but well rising starter and it just seems odd that mine is doing the opposite! I wonder why this is. Thanks
The whole rising thing is about bubbles. Yours are small, probably due to slightly high hydration.
The hydration is 100% by weight. There are a lot of large bubbles on the surface, but virtually none in the rest of the starter. All the pictures I see of strong, active starters have bubbles in the entire body.
Try adding a bit of wholewheat...
