Step 1

Pinch off each leaf, including the stem, from the main stalk and any other tender parts of the vegetables. Wash and rinse thoroughly a couple of times and set aside to drain off any excess water before cooking.

Step 2

Heat the oil in a wok over medium heat. Add the garlic and ginger, and cook for about a minute. Now turn the heat to high, and add in the sweet yam leaves.

Step 3

Stir and add in the sesame oil, Shaoxing wine (optional), ground white pepper, water, salt (to taste) and a pinch of sugar. Stir to cook for a couple of minutes until all the leaves are wilted. Serve immediately.
