About Proof of Concept

Proof of Concept is a sourdough newsletter for people who like clear methods, honest results, and zero fluff.

Tagline: Clone the starter, share the crumb.

What we do

• Publish repeatable recipes with timings, temps, ratios, and schedules.
• Share full method notes—what worked, what didn’t, and why.
• Post crumb shots and autopsies when a loaf goes sideways.

How we operate

• Open by default. You can copy, remix, and credit.
• Independent & ad-free. Reader support keeps the oven hot.
• Baked in public. Drafts, tests, and final bakes are all visible.
• Community in the loop. Your tweaks and failures feed the next issue.

What we’re not

• Not a guru channel.
• Not gatekept, paywalled, or optimized for “engagement.”

Who it’s for

Home bakers who want method over mystique and bread that improves week to week.

If this helps you level up your loaves, tell a friend or chip in.
If it doesn’t, tell us what broke—we’ll publish the fix.

Open kitchen. Honest bread.
