Description
A layered fermentation technique that creates complex umami through controlled heat transfer in stoneware.
Technical
Gradual thermal transfer through porous stone activates glutaminase enzymes in doenjang, converting glutamine to glutamic acid while preserving heat-sensitive Bacillus subtilis probiotics. The stone pot's alkaline minerals (calcium/magnesium oxides) buffer acidity during slow simmering.
Culinary Significance
Creates deeper flavor integration than standard stew methods, allowing individual ingredients to contribute distinct notes while forming a unified broth.
