Dim sum (點心 — literally "touch the heart") — the Cantonese tradition of small, shared dishes served with tea — developed from the yam cha (飲茶 — drinking tea) culture of Cantonese teahouses. The tradition encompasses over 2,000 named preparations across its full breadth; the core techniques involve the most demanding dough manipulation in Chinese cooking.
The dim sum tradition — its techniques and its principal preparations. **蝦餃 (Har Gow — Shrimp Dumpling):** The benchmark preparation against which a dim sum chef is judged — translucent wheat starch dough (not wheat flour — wheat starch produces the specific translucency that regular flour cannot) folded into pleated crescents around a whole shrimp filling. The technical standards for professional har gow: - The dough must be translucent — any opacity indicates incorrect wheat starch ratio or incorrect temperature control during mixing - Seven pleats minimum on each dumpling — each pleat folded in the same direction, same size - The shrimp must be visible through the dough when held to light [VERIFY] - The skin must be thin enough to be translucent but thick enough not to tear when picked up with chopsticks **叉燒包 (Char Siu Bao — BBQ Pork Bun):** Two styles — steamed (white, soft skin that splits on top to reveal the filling) and baked (glazed, golden). The steamed version's split is not a failure but a deliberate technique: the dough is leavened with a specific combination of baking powder and yeast, and the split reveals the red, sweet filling inside — the split is the visual signal of correctly made bao. **燒賣 (Siu Mai — Pork and Shrimp Dumpling):** The open-topped dumpling — minced pork and shrimp filling placed in a wonton wrapper, the edges pleated upward to form a basket shape but the top left open. The filling must be slightly mounded above the wrapper level — flat-topped siu mai is under-filled. **蛋撻 (Dan Tat — Egg Tart):** The Cantonese Portuguese egg tart — a shortcrust pastry shell filled with a smooth, barely-set egg custard. The Portuguese tart (pastel de nata) was transformed in Macau and Hong Kong into the Cantonese egg tart through the colonial exchange. The Cantonese version uses a more neutral, less caramelised custard than the Portuguese original.
