Hulled corn kernels cracked into coarse pieces, soaked overnight and simmered low and slow for hours with red beans until the gruel thickens to a deep golden, powerfully filling porridge. The backbone of the Dongbei breakfast table—rough-grained and elemental, a relic of the cold-climate staple diet when corn was the North's answer to rice.
Corn reached China's northeast after its 16th-century introduction from the Americas via Silk Road and maritime trade. By the Qing dynasty, the Three Eastern Provinces had become a principal corn-growing region—Heilongjiang and Jilin straddle one of the world's three major golden corn belts—and corn-based staples became essential winter provisions for ordinary households unable to afford polished rice. Coarse corn porridge represents the most enduring of these preparations: whole corn soaked and simmered into a filling gruel that could sustain a family through months of bitter cold. The deliberate coarse grind preserves more kernel fiber and gives the dish its characteristic bite and staying power, distinguishing it from fine cornmeal congee.
Warm, thick, faintly sweet with the low golden note of field corn. The grits offer gentle resistance before yielding, and the red beans add earthy softness. It coats the stomach immediately—dense and elemental, like eating the season's grain reserves in a single bowl.
The long soak hydrates the dense, de-hulled corn kernels and begins softening the cell-wall matrix. During extended low-heat simmering, starch granules within the corn swell and gelatinize into a viscous continuous phase—without full hydrolysis, they retain a pleasant bite rather than turning to mush. Red bean starch and protein leach into the broth, enriching body and color. A key nutritional note: corn's niacin is largely bound as niacytin, biologically unavailable in plain cooking; adding a pinch of baking soda alkalizes the liquid and releases free niacin—an empirical practice in some Dongbei kitchens that mirrors the ancient Mesoamerican nixtamal process in function if not in method.
Variations
With mung beans: a cooling summer variant. With red dates and peanuts: sweeter, served on festival mornings. Fine-ground version (小碴粥): smoother and quicker but loses the characteristic bite. Pressure-cooker method: ready in 40 minutes, a modern shortcut without the slow-rendered depth. Some families add a pinch of baking soda to improve niacin bioavailability.

Ingredients
Serves 4How it's made
7 steps · 10 min
- 13 min
Measure 1 cup coarse corn grits (大碴子) and 3 tbsp adzuki red beans; rinse under cold water.
- 2240 min
Transfer to a bowl; cover generously with cold water and soak at least 4 hours or overnight until the corn pieces visibly swell and soften slightly.
Watch outSoak the grits until the kernels visibly swell and soften — skip this and they never turn creamy, staying hard at the center however long you simmer.
- 35 min
Drain the soaking water; transfer corn and beans to a heavy-bottomed pot; add 8 cups fresh cold water.
- 410 min
Bring to a full boil over high heat; skim any foam and stir the bottom to prevent sticking.
- 5150 min
Reduce heat to the lowest setting; prop the lid slightly ajar; simmer 2 to 2.5 hours, stirring every 20 minutes.
Watch outKeep it at the lowest simmer with the lid ajar and stir every so often — walk away and the starchy bottom scorches and turns the whole pot bitter.
- 65 min
The porridge is ready when it is thick and golden-tinged and the corn kernels have bloomed and swelled but hold their shape with a gentle bite.
Watch outIt's done when it's thick and golden and a spoon dragged across meets real resistance, the kernels bloomed but still holding a gentle bite.
- 72 min
Season with a pinch of salt if desired; ladle into deep bowls and serve hot.
