Fried Tofu Balls

Fried tofu balls are a Guiyang specialty, most famously the 'Leijia tofu balls' (雷家豆腐圆子) sold by the Lei family, a shop whose history in the city is generally given as reaching back into the late Qing, around the Guangxu era of the 1870s–80s; the precise founding date is told differently in different accounts. Local lore ties the snack's rise to a fast-day work-around — when meat was off the table, fried tofu balls stood in for fried meatballs — a neat story that is folk tradition rather than documented fact. What is solid is that the dish became one of Guiyang's signature xiaochi, a fixture of its snack streets, with the Lei family name long synonymous with the best version. It belongs to a wider family of Chinese fried tofu balls, but the Guiyang style is defined by its airy, blistered texture and its fish-mint sour dip.

The shell shatters thin and crisp under the teeth, deep golden and faintly chewy, while inside the tofu is soft, hot and lightly spongy, riddled with little air pockets that soak up the dip. The tofu itself is mild and savory, scented with scallion; the fun is the contrast of crackle and pillow. Then comes the dip — sour with vinegar, hot with chili, sharp and herbal with raw fish mint and garlic — cutting the richness of the fry and waking the whole thing up. Eaten piping hot, split and dunked, it is crisp, soft, sour and spicy all at once.

Everything turns on getting a soft, airy interior under a crisp shell. Firm or pressed tofu is squeezed of excess water and mashed fine, then beaten well so the bean curd loosens into a cohesive, slightly sticky mass that will hold a ball yet stay tender — the beating, and sometimes a pinch of baking soda, work air and lightness in so the fried interior comes out spongy rather than dense. A little starch and seasoning bind and flavor it. Frying then sets the outside before the inside overcooks: in hot oil the surface dehydrates and browns into a crisp, Maillard-toasted shell while steam puffs the inside, opening up the honeycomb. Frying too cool leaves them greasy and pale; too hot scorches the shell before the center sets, so a steady medium-hot oil, and sometimes a second quick fry, gives the best crackle. The sour-spicy dip is raw and uncooked, so its fish mint, garlic and vinegar stay sharp against the hot, oily balls.
