Sourpuss mascot, a grumpy little dough blob

Sourpuss Starter Club

We're turning everyone sour.

We rolled our eyes at sourdough people for years. Then we caved. So did you. Might as well be a Sourpuss about it: no snobs, no obsessive math, just you, a grumpy little blob, and a club that laughs at its own flat loaves.

Know zero about sourdough? Perfect. Start here:

The Blob Tracker

Feed your starter, slide in the rise, and know when it's peak puffy.

Kitchen weather

Hot, cold or muggy? We tell you how your blob will behave today.

Bake-day timers

Autolyse, folds and bulk — one friendly nudge at a time.

The Blob Board

Crumb Shots, Flat Flops and Discard Dispatches from fellow Sourpusses.

Great. Another one who caved. Welcome, Sourpuss.
