牛奶成扇,炭火烤香。Níunǎi chéng shàn, tànhuǒ kǎo xiāng – Milk is drawn into a fan; charcoal fire toasts it fragrant.
乳扇 Rǔshàn “milk fan” is the cheese of the Bai – fresh milk curdled with 酸浆 suānjiāng acid whey, pulled by hand into thin translucent sheets and dried slung over bamboo, the fan shape giving it the name. It comes from 邓川 Dèngchuān in the plum country north of Dali, and Dali eats it two ways: raw from the market, or grilled over 炭火 tànhuǒ charcoal on a street stall, brushed with 玫瑰糖 Méiguī Táng rose syrup and rolled onto a stick. A grilled fan runs about 5-10 yuan depending on size, and the honest shape is that this is a lactic curd, faintly sour on its own, made sweet by fire and rose. Eaten raw, a dried sheet is torn into strips and dressed with sugar; eaten grilled, it is the stick in every tourist photo, which is the version locals actually buy.

The mechanism is acid, not rennet. The 酸浆 suānjiāng is the whey left from a previous batch – soured with 木瓜 mùguā papaya acid in the old method – which curdles the warmed milk into a loose gel that a cook pulls and folds into a sheet before it sets hard. Dried, it keeps; reheated, it softens into a chewy, smoky ribbon. The craft is said to have travelled into Yunnan with the Mongol-era cheesemakers of the thirteenth century (a theory, not a record), and the point is that the same sheet becomes three different things: 烤乳扇 kǎo rǔshàn grilled on the street, 炸乳扇 zhá rǔshàn deep-fried on restaurant plates, and 生乳扇 shēng rǔshàn raw at home with sugar.

Locals eat it standing. Watch the stall: the fan goes flat on the grill, blisters, gets painted with rose syrup, then is rolled in one motion – and it is only right hot, because it stiffens into a chew when it cools. The stalls cluster along 复兴路 Fùxīng Lù and 人民路 Rénmín Lù in the old town; raw sheets for the kitchen are sold at the north-gate market; and the name to ask for is still 邓川 Dèngchuān even though most of what you meet is made locally. Pair it with the 三道茶 Sāndàochá three-course tea if you want the full Bai table, and ask the per-piece price before you order three. The shelf life is short in humid weather – a dried fan keeps, a grilled one does not – which is why the stalls sell by the piece and the markets by the bundle. If you like it sweeter, ask for extra 玫瑰酱 méiguī jiàng – the syrup is the only sugar on the stick.

What the Locals Know
The local knowledge about the fan is about the heat and the roll, and it is the same check a Dali regular makes at any stall. The fan is only right hot – it stiffens into a chew when it cools, which is why locals eat it standing off the stick rather than sitting down to a plate. The second check is the stall’s motion: the fan goes flat on the 炭火 tànhuǒ, blisters, gets painted with 玫瑰糖 Méiguī Táng rose syrup and is rolled in one movement, and a cook who fumbles the roll is not worth the queue. The third is the name and the form: ask for 邓川 Dèngchuān even though most of what you meet is made locally, take the grilled by the piece at the stall and the raw sheets by the bundle at the market, because the honest shape is that a dried fan keeps and a grilled one does not.

flowcloud would say that rushan is the Bai answer to cheese – milk curdled with papaya whey, pulled into a fan, grilled over charcoal and painted with rose syrup – and that the honest move is to eat it off the stick while it is still hot, because the fan is the shape and the charcoal is the cook.
