Sam Kap Dai Soup

Sam Kap Dai is documented as a Han Hakka dish of eastern Guangdong, named after the imperial examination: in the civil-service era 三及第 referred to passing as a scholar, then provincial graduate, then metropolitan graduate in succession (one reading), or to the top three palace-exam ranks of zhuangyuan, bangyan and tanhua (another). Chinese sources tie the name to the Qing-dynasty zhuangyuan Lin Zhaotang of Wuchuan, who is said to have favoured a congee of three pork organs likened to the three ranks; a later Jiaoling scholar is recorded as reworking that congee into a soup of pork loin, liver and intestine, keeping the auspicious name. The Jiaoling version of the soup carries roughly two hundred years of history and was listed among Guangdong's provincial intangible cultural heritage in 2015. A separate Cantonese tradition of 三及第 also exists in the form of congee and lai-fun, but the Hakka soup is the form centred here; the meats and greens vary by household and county.

The broth is clear and light, sweet from bone stock and a touch of pickled mustard, never heavy. Each spoonful gives three textures at once: silky liver that barely yields, tender slices of lean pork, and springy-but-clean intestine with a faint offal richness. The goji or sweet-potato leaves add a fresh, slightly grassy bitterness that cuts the meat; enoki, if used, lend a soft slither. It eats hot, brisk and restorative — a morning soup, not a slow tonic.

Everything depends on cooking the organs only to the point of doneness in already-boiling liquid. The lean pork is sliced thin and tossed with a little sweet-potato or potato starch: the starch gelatinises on the surface and seals in juices, so the slices stay tender rather than seizing. Liver is added last and for the shortest time — held past raw but well short of overcooked, so its proteins set just enough to turn silky while staying pink, since prolonged heat makes it grainy and chalky. The intestine is the cleaning job: scraped and washed until odour-free, then cut and cooked briefly so it stays springy, not tough. A spoon of fermented rice brine (糟汁) and pickled mustard season the broth and lend gentle acidity and depth, while the goji or sweet-potato leaves go in at a rolling boil for only seconds to keep their colour and fresh edge.
