糖水 — Cantonese dessert soups
Tong sui literally means "sugar water", but it's the family of sweet soups Cantonese people eat in the evening — the genuine heritage, decades older than coffee.
Double-skin milk (双皮奶) — the best-known of all the Cantonese dessert soups, eaten warm or chilled
The most famous dessert soup of all — milk steamed with egg white until two layers of "skin" form, leaving a custard as smooth as panna cotta but only faintly sweet. It originated in Shunde (顺德), Guangdong, in the late Qing dynasty and was traditionally made with water-buffalo milk. Eat it warm in the evening or chilled in summer; some bowls come topped with red beans or osmanthus. If you try only one 糖水 in Guangzhou, start here.
A dessert that works like a small piece of magic — hot milk is hit straight into fresh ginger juice in the bowl, and within a few minutes an enzyme in the ginger sets the milk into a soft pudding on its own, with nothing else added. The texture is close to double-skin milk, but with a warm gingery edge that cuts the richness and a faint heat at the tip of the tongue. Cantonese people eat it when the weather turns cool or their stomach feels off.
Roasted black sesame ground fine and simmered into a thick sweet porridge — jet black, deeply nutty, silky-smooth and slipping down easily. It's one of the most comforting of all the dessert soups, and Chinese tradition holds that black sesame is good for the hair and the body. Some shops serve it alongside a white almond paste (杏仁糊) poured into the same bowl in a black-and-white swirl that locals call the "yin-yang" pairing.
A black jelly made from a blend of Chinese herbs, with a distinctive faint bitterness. Cantonese people eat it to "clear heat" from the body in the logic of traditional medicine. The texture is like grass jelly but firmer, and it's usually drizzled with honey or syrup to make it easier going. That bitter edge isn't for everyone at first bite, but plenty of people grow to love it for how refreshing and un-cloying it is.
The cool, refreshing side of the dessert soups — sago (西米露), little translucent pearls bobbing in coconut or milk, often with fresh mango or, in the deluxe version, durian. Red-bean soup (红豆沙) is adzuki beans simmered down to a thick, gently sweet pour — a true classic. Both are the bread-and-butter of every dessert house, cheap and easy to like, and a good first bowl if you're not yet used to Cantonese desserts.
The warming, belly-settling end of the spectrum — glutinous rice balls (汤圆) filled with black sesame or peanut, floating in warm ginger broth, and sweet-potato soup (番薯糖水), orange sweet potato simmered with brown sugar and ginger until the clear amber liquid turns fragrant and lightly spiced. These are the homely desserts every dessert house keeps on the menu, especially in winter when Guangzhou wants something warm.
