Napa Cabbage and Tofu Stew

Napa cabbage became a cold-season staple of northern China from the Ming dynasty onward, stored in earthen pits through winter. Tofu's origin is traditionally attributed to Han-dynasty Prince Liu An (相传约前一六四年前后）, though this claim is debated by food historians; what is well-documented is that tofu had become a widespread northern protein staple by the Song dynasty (960–1279). The two were combined in winter stews as a natural pairing: cabbage sweetens during long braising, and tofu absorbs the resulting broth. Qing-dynasty household writings document this combination as standard winter fare, and it remains virtually unchanged today.

Translucent, silky cabbage leaves in a clean, faintly sweet broth alongside creamy tofu cubes — warming, nourishing, and as comforting as any winter stew can be.

Napa cabbage is nearly 95% water. Extended simmering (15–20 min) breaks down its pectin matrix, releasing glutamic acid and sweetening compounds into the broth; the leaves become translucent. Firm tofu is a protein gel (soy proteins crosslinked by calcium sulfate) that swells slightly when heated in broth, developing a porous interior — especially pronounced in frozen tofu (冻豆腐), where ice crystal formation creates large interconnected channels that dramatically increase broth absorption. Pork bones contribute glutamates and collagen hydrolysate that thicken and enrich the otherwise light vegetable stock.
