Dengzhan Rice Cakes

Dengzhan rice cakes are a folk rice snack of Jiangxi, best documented as a specialty of Yanshan County in Shangrao in the northeast of the province; their exact origin is not recorded. The name simply describes the form — a little rice cup shaped like an oil lamp of the old kind. A local legend credits an innkeeper's wife with first shaping rice paste into the lamp form and filling it, the snack later named by a passing emperor traveling incognito; this is told only as folklore and is not documented. Similar lamp-shaped rice cups are made in other parts of Jiangxi, including the Ji'an region to the south, with their own fillings, so the dish belongs broadly to the province rather than to a single town.

The cup is the texture of cooked rice pressed firm — soft and faintly chewy, a little dense in the thick rim, holding its shape under the filling. Inside sits a warm, savory tumble of diced vegetables and meat, the radish and peas sweet, the mushroom earthy, the pork giving richness; the spoonful of pork fat melted over the top binds it and lends a glossy, fragrant finish. The mild rice cup is the foil to the seasoned filling, the two eaten together in one bite. Hot from the steamer the cup is tender and the filling juicy; gone cold the rice firms as its starch sets, so it is eaten warm, the lamp turned out whole and eaten in a few bites.

The cup holds because the rice starch is gelatinized before shaping. Rice ground to a slurry or flour and stirred over heat into a stiff paste has its starch fully gelatinized and water-bound, turning sticky and moldable; pressed into a thick-walled cup while warm, it sets firm enough to hold a wet filling through steaming, where the gel firms further into a tender, cohesive shell. Rice has no gluten, so it is this gelatinized, partly retrograding starch that gives the cup its strength and chew rather than any elastic dough. The filling is stir-fried only to near-done first, because the final steam finishes it without overcooking, and the rendered pork fat spooned on at the end carries fat-soluble aroma and coats the filling with gloss and savor. Eaten hot before the starch retrogrades and toughens, the cup stays soft.
