What is it?
Water spinach is the official Hong Kong market English name for 通菜. It is also called ong choy, morning glory, swamp cabbage or kangkung.
How to identify it
Look for long tender stems with a clearly hollow centre, visible nodes and pointed green leaves. It is not ordinary spinach despite the English name.
- Long stems with a hollow tube
- Pointed or arrow-shaped leaves
- Visible nodes where leaf stalks emerge
Common confusion
Water spinach has long hollow stems; Chinese amaranth normally has solid stems and different leaf veins.
Common Hong Kong household uses
Commonly stir-fried with garlic, fermented bean curd or shrimp paste.
Preparation or handling
Remove tough stems and yellow leaves, inspect each section, wash thoroughly under running water and drain before quick cooking.
Storage
Keep unwashed and dry in the refrigerator and use quickly. Wrap cut portions and refrigerate.
Helper tip
Chinese amaranth normally has solid stems rather than a hollow tube. Break one stem or ask the employer if unsure.
What Ma’am or Sir may say
