Kaifeng Soup Dumplings

Kaifeng's signature soup dumpling lineage runs through the First Tower (第一楼) restaurant, whose founder Huang Jieshan opened a bun shop in 1922 (renamed First Tower in 1933) and later perfected the form by switching from half-leavened to unleavened (dead) dough for the thinner skin. They differ from Shanghai xiaolongbao in scale: each Kaifeng guantangbao is roughly twice the size, with a thinner wrapper and proportionally far more soup, closer to Tianjin's goubuli baozi in scale than to xiaolongbao. Kaifeng was the Northern Song capital; the soup-dumpling craft traces back to that imperial-kitchen lineage.

Kaifeng's First Tower (第一楼) has made these since 1922 — twice the size of Shanghai xiaolongbao with a 1:1 aspic-to-meat ratio (Shanghai runs 1:2). Eighteen pleats spiraling to a tiny knot is the form.

The dumpling arrives in a bamboo basket the size of a small saucer, eighteen pleats spiraling to a tiny knot. You lift it on a spoon — never with chopsticks alone, the skin will tear — bite a small hole at the side, and sip the broth first. It is scaldingly hot, pork-rich, almost amber. Then eat the wrapper and meat together with black vinegar and shredded ginger. If broth pools in the basket instead of inside, the cook over-steamed.

The aspic-as-soup trick is the load-bearing technique: cold pork-skin (and often chicken) aspic is solid at room temperature, so it can be wrapped, but melts above 60°C, so during steaming it liquefies inside the sealed wrapper. Aspic-to-meat ratio is the variable — Shanghai xiaolongbao runs about 1:2, Kaifeng runs 1:1, which is why these have noticeably more soup. Hand-mince the pork instead of grinding, or the meat won't trap the soup against the skin.
