Takeaways
Strong rise from ending the bulk fermentation when I did and doing a longer cold proof (18h). The sour flavor is still mild so I’m glad I did a longer cold proof.
The rosemary overpowers the polenta flavor but it’s really pleasant. The polenta made the crust a little crispier/flakier which is interesting.
Very mild acidity, wheaty and herbal, crumb soft but resilient, crust shatters slightly on bite.
