I use Sourdough Starter to make this cheesy bread.
Sourdough starter acts as the primary chemical and structural engine in this dough, supplying wild yeasts and lactic acid bacteria that naturally condition the gluten network before commercial inoculants existed. Historical frontier baking frequently relied on this dual-action fermentation to aerate dense, enriched doughs containing heavy fats like butter and cheese, which would otherwise suppress rise. Incorporating sharp cheddar and cured pork directly into the matrix creates pockets of savory moisture throughout the crumb. Adding baking soda alongside the fermented starter neutralizes excess acidity from the wild culture, ensuring the crumb structure remains tender rather than overly dense.
Allowing the shaped loaves to ferment undisturbed for two hours in a draft-free environment ensures the wild yeasts produce sufficient carbon dioxide for maximum oven spring. Preheating the oven to 375 degrees Fahrenheit provides the thermal energy required to set the protein structure rapidly before the fats liquefy completely. Covering the top with aluminum foil partway through the 30-minute bake prevents excessive Maillard browning of the dairy solids and sugars present in the batter. Kneading requires holding back approximately one-half cup of all-purpose flour to prevent the moisture level from dropping too low, ensuring the final loaves maintain a soft and elastic interior crumb.
