Guizhou potato cake is a humble highland street snack of mashed potato pressed into small flat cakes and griddle-fried until crusty and golden on both sides. Steamed potato — the staple of Guizhou's cool uplands, where it is called 'yangyu' — is mashed with a little scallion and seasoning, shaped into patties and fried on a griddle or pan with a film of oil. Crisp outside and soft inside, the hot cakes are showered with toasted chili powder, salt and crushed Sichuan-pepper-and-chili 'dip salt,' sometimes brushed with chili paste. Cheap, smoky and filling, they are a stalwart of Guiyang and mountain-town snack stalls.
Guizhou potato cake belongs to the province's mountainous interior, where the potato — a New-World crop that spread through China's southwestern highlands from the late Ming and Qing — took hold as a dependable staple in cool, thin-soiled hill country and gave Guizhou, Yunnan and Sichuan a whole genre of 'yangyu' dishes. Mashing the surplus or the small, knobbly tubers into a cake and frying them is a practical, thrifty way to make a filling snack, and like most such folk foods it carries no founding story or date. In Guiyang and the upland market towns it became a street-stall standby, cheap and quick, its appeal sharpened by the heavy hand of toasted chili-salt that is the Guizhou seasoning signature. It sits within the family of Chinese fried potato cakes, distinguished by that dry chili dip.
Griddled crisp and golden, the cakes give a thin crackle at the edge then yield to a soft, steamy, faintly sticky potato middle, plain and comforting on its own. The seasoning is everything: a heavy dusting of toasted chili powder and salt, often with ground roasted Sichuan pepper, lands hot, smoky and a little numbing on the crust, and a smear of chili paste adds fragrance and a sour-spicy edge. The contrast of crisp shell, fluffy inside and fiery dry dip is the whole charm. Eaten straight off the griddle, blowing on your fingers, it is rib-sticking and unpretentious.
It works on the starch in the potato. Steaming or boiling the potato fully gelatinizes its starch, so when mashed it turns soft and binds into a cohesive patty that holds together on the griddle without flour or egg — a starchy waxy potato mashes stickier and holds best, a floury one stays fluffier. Mashing while hot keeps it cohesive; overworking a floury potato can turn it gluey, so a light hand suits. On the griddle a film of oil and steady medium heat dehydrate and brown the surface through the Maillard reaction into a crisp golden crust, while the inside stays moist and soft; pressing the cakes thin gives more crust to soft-center ratio. The chili-salt dip is dry-toasted, which both cooks off the chili's raw edge and draws out its color and aroma, and it is added at the end so it stays crisp and pungent on the hot cake rather than dissolving in.
Variations
The constant is mashed potato fried into cakes and hit with toasted chili-salt; the variables are texture, additions and dip. Some cooks keep the mash smooth, others leave it chunky or fold in scallion, chopped pickle, suancai (sour greens) or even a little ground meat or cheese-like 'milk fan' across the Yunnan border. The cakes may be small and thick or large and thin; cooked on a flat griddle, a domed pan or shallow-fried. The dip ranges from plain chili-salt to a fuller mix with ground roasted soybean, MSG and Sichuan pepper, and a brush of chili paste or fermented sauce is common. It should not be confused with Yunnan's 'lao nai yangyu,' a soft mashed-potato stir-fry rather than a fried cake; the Guizhou snack is defined as a crisp griddle cake eaten with dry chili-salt.

Ingredients

6 steps · 35 min
- 18 min
Peel the potatoes, cut into chunks, and steam or boil until completely soft.
- 26 min
Mash the hot potato until smooth and cohesive, then mix in chopped scallion and a little salt.
Watch outMash the potato while it's hot and work it lightly — hot mash binds into a patty that holds on the griddle, but overworking a floury potato turns it gluey.
- 34 min
Make the dry dip: dry-toast chili powder (and Sichuan pepper, if using) with salt, or have toasted chili-salt ready.
- 45 min
With lightly oiled hands, shape the mash into small flat cakes, pressing them an even thickness.
- 510 min
Heat a griddle or pan with a film of oil over medium heat and fry the cakes until crisp and golden on both sides.
Watch outFry over medium heat until crisp and golden both sides — steady heat browns the surface into a crust while the inside stays moist and soft.
- 61 min
Sprinkle the hot cakes generously with the toasted chili-salt (and brush with chili paste if liked) and serve at once.
