Quick Answer: What Is Chinese Water Chestnut Sweet Soup?
Chinese water chestnut sweet soup is a dessert with chopped water chestnuts in sweetened water, often lightly thickened. Names include ma ti lu (马蹄露, mǎtílù) and ma ti shuang (马蹄爽, mǎtíshuǎng). Its appeal combines crisp vegetable pieces with a smooth liquid base.[1][2][6]
- Pieces: Peeled water chestnuts, chopped or crushed for a crunchy bite.
- Liquid: Sugar and water, with starch used in many preparations.
- Additions: Egg ribbons, beans or flavorings, depending on the version.
Egg is not a universal ingredient, and the dessert can be served warm or chilled. Confirm the actual bowl rather than assuming one fixed formula.[1][3][6]

Tiny crisp pieces and silky liquid give water chestnut sweet soup its contrast. Egg ribbons may float through it, while other versions leave out egg. Separating pieces, thickener and additions makes this understated Chinese dessert easier to recognize.
Water Chestnut Pieces and Starch Do Different Jobs
The water chestnut used here is a crisp, white aquatic vegetable. Chopping leaves small pieces to bite into; a finer puree produces a smoother result. Fresh and frozen peeled water chestnuts both appear in documented preparations.[1][2]
Water chestnut powder has another job. Mixed with water and heated in the soup, the starch thickens the surrounding liquid. It does not replace the chopped pieces or supply the same crunch. Some preparations use cornstarch instead, while one recipe treats thickening as optional.[2][4]
A thicker soup still remains spoonable. Ma ti gao (马蹄糕, mǎtígāo), or water chestnut cake, is a different finished form: a steamed, set starch-based cake that can be cut into pieces. [6]
Egg Ribbons, Beans and Floral Variations
These examples separate the basic bowl from added beans, leaves or flowers:[1][3][5][6]
| Documented preparation | Ingredients or additions | Texture or aroma |
|---|---|---|
| Simple water chestnut sweet soup | Water chestnut pieces, slab sugar, starch and water. | An egg-free preparation centered on the chopped vegetable. |
| Split mung bean version | Peeled split mung beans and egg. | Soft beans alongside crunchy pieces and egg ribbons. |
| Pandan and goji version | Pandan leaves, goji berries and egg white or whole egg. | A fragrant liquid with additional soft pieces. |
| Osmanthus version | Osmanthus flowers and beaten egg. | A floral variation with delicate egg swirls. |
Egg added to the hot liquid forms fine cooked strands rather than a whole custard. Egg white or whole egg can be used. Optional custard powder appears in another version for added flavor and a deeper yellow color.[2][3]
The osmanthus-flavored version uses flowers for aroma. [5]
Home Desserts and the Menu-Name Question
The soup belongs to the broader Chinese sweet-soup tradition. Home accounts describe it as a childhood dessert, a family serving during a Hong Kong summer, and an after-meal sweet. It forms part of Hong Kong food culture as well as broader Chinese home cooking.[1][2][3]
Names can be less precise when ordering across places. In one Ipoh dining experience, a request intended for the chopped-water-chestnut egg dessert produced a water chestnut drink instead. Confirming a spoonable dessert with pieces is more useful than relying on a translated name alone.[4]
How to Order and Eat Water Chestnut Sweet Soup
Use the full dessert name and check three things: whether it contains chopped pieces, how thick the liquid is, and whether egg or other additions are included. Then choose warm or chilled serving if offered.
For vegetarian or vegan choices, ask directly about egg and any compound powders. Egg-free recipes exist, but removing visible strands does not establish that egg was absent from the mixture. [2][6]
Eat a spoonable version with a dessert spoon, taking some liquid and chopped pieces together.
