Method
- Wash the sweet potato leaves thoroughly. Pluck the leaves from the woody stems; tender stems can stay. Discard any yellow or limp leaves. Pat completely dry — wet leaves steam in the wok instead of frying.
- Heat oil in a wok over the highest possible flame. Add garlic; stir for 5 seconds — the kitchen should fill with the garlic smell almost immediately. Don't let the garlic brown.
- Add the sweet potato leaves all at once. Toss vigorously with chopsticks (not a spatula) for 90 seconds. The leaves should wilt rapidly and shrink dramatically.
- Add soy sauce, sugar, salt and white pepper. Splash in the 30ml water; this creates a quick steam burst that ensures the leaves cook evenly without burning.
- Toss for another 30 seconds. The leaves should be wilted but still vivid green; the pan should be just barely wet, not saucy.
- Off the heat, drizzle sesame oil and toss once. Plate immediately; sweet potato leaves wilt further if left sitting. Serve as part of a Taiwanese family-style meal with rice and other dishes.

Cultural Note
Sweet potato leaves are Taiwan's daily green vegetable ? ironic given that Taiwan was once nicknamed 'sweet potato' for its shape on the map. The leaves grow vigorously and produce far more than the tubers in suitable climate. The stir-fry technique is universal: high heat, garlic, soy, sugar ? almost any tender Asian green can be cooked this way. The slightly sweet flavour and tender texture distinguish them from spinach. The dish appears at almost every Taiwanese household dinner.
