This guide details a rigorous, data-driven system to move beyond visual guesswork, ensuring every batch of sourdough English muffins achieves perfectly cooked centers and the iconic, craggy architecture of nooks and valleys.
The most significant breakthrough is using an instant-read thermometer to target exactly 200°F internally, eliminating the risk of a raw core. For best results, ensure your room temperature is between 65-70°F during the 8-12 hour proof. If centers are raw, your heat is too high; if nooks are missing, check starter activity or proofing time. Store leftovers sliced in the freezer for long-term freshness.
