Why this works
Cao tou — clover greens, a Shanghai spring favourite — is the reason this dish exists: tender, slightly sweet leaves that wilt in twenty seconds and need nothing more than a hot pan. The report pairs them with beef cut along the grain into five-to-seven-centimetre shreds, marinated with soy, wine, starch and exactly one gram of baking soda. That gram is the dish's secret and its warning: weighed precisely it tenderises, guessed it makes the beef taste bitter and soapy. The cooking is split on purpose — beef slid at 150 °C for thirty seconds and removed, greens fried alone on fierce heat for twenty seconds, then everything reunited for a ten-second toss in a premixed oyster sauce. Pouring the sauce in all at once, not in stages, is what lets it coat instead of pooling. Served with greens on the bottom and beef on top, eaten immediately before the greens release water, it is a fifteen-minute Shanghai home dish that depends entirely on heat, timing and one carefully weighed gram.

Ingredients
| Ingredient | US | Metric | Substitute / note |
|---|---|---|---|
| Beef leg meat, cut into shreds 5-7 cm long | 5.3 oz | 150 g | Cut along the grain, per the report. |
| Clover greens (cao tou), old roots removed | 7 oz | 200 g | Wash and drain well, keeping tender stems and leaves. Baby spinach is the closest substitute (adaptation). |
| Light soy sauce, for marinating | 2 tsp | 10 ml | — |
| Cooking wine, for marinating | 1 tsp | 5 ml | — |
| Corn starch, for marinating | 1 tsp | 5 g | — |
| Baking soda | 1/4 tsp | 1 g | Weigh it exactly; do not guess. More makes beef bitter, per the report. |
| Oyster sauce | 1 oz | 30 g | — |
| Sugar | 2 tsp | 10 g | Balances the salt in the oyster sauce. |
| Light soy sauce, for the oyster sauce | 1 tbsp | 15 ml | — |
| Water starch (10 ml water + 10 g starch) | 4 tsp | 20 ml | For thickening the sauce. |
| Neutral cooking oil | 3 tbsp + 1 tsp | 50 ml | 30 ml for sliding the beef, 20 ml for the greens. |
Equipment
- Large skillet or wok — no wok required (adaptation)
- Small bowl for the oyster sauce
- Kitchen scale for the baking soda
Steps
- Marinate the beef. Cut the beef along the grain into shreds 5 to 7 cm long. Toss with 10 ml light soy, 5 ml cooking wine, 5 g starch and exactly 1 g baking soda, mixing until sticky. Rest 5 minutes.
- Mix the oyster sauce. Combine the oyster sauce, sugar, 15 ml light soy and water starch into a bowl sauce and stir until smooth.
- Slide the beef. Heat 30 ml oil to 150 °C (just shimmering). Slide in the beef shreds and stir quickly until they just change colour, about 30 seconds. Remove at once; the beef must be fully cooked through with no pink remaining, per the report — if shreds are thick, give them a few seconds more.
- Fry the greens. In a clean pan with 20 ml oil heated until smoking, add the clover greens and stir-fry on high heat 20 seconds until bright green and just wilted. Remove and drain.
- Combine. Return the beef to the pan, pour in the whole bowl of oyster sauce at once, and stir on high heat 10 seconds until the sauce coats everything. The beef centre must reach at least 75 °C, per the report. Plate with greens on the bottom and beef on top, and serve immediately before the greens release water.

Technique: one gram, ten seconds
Baking soda is measured, not estimated: 1 g tenderises 150 g beef, and even a little more leaves a bitter, slippery taste that no sauce covers. The final toss is ten seconds because the sauce is premixed and the starch thickens instantly — poured in stages, it never coats evenly, and the greens sit in a puddle instead of under a glaze. Greens must be drained well and the pan smoking hot, or they steam yellow instead of wilting green.
Variations
- Substitute greens: baby spinach or pea shoots, fried the same 20 seconds, if clover greens are unavailable (adaptation).
- No baking soda: omit it and velvet with egg white instead; the beef will be slightly less tender but still good (adaptation).
Frequently asked questions
What are clover greens?
Cao tou is a tender Shanghai spring green, sold in Chinese groceries in season; baby spinach is the closest everyday substitute.
Why does my beef taste bitter?
Too much baking soda — weigh exactly 1 g for 150 g beef, about a quarter teaspoon, levelled.
Why did my greens go yellow?
The pan was not hot enough, or they were fried longer than 20 seconds, or they were wet going in. Drain well and use fierce heat.
Storage and freezing
Best eaten immediately. Leftovers keep 1 day refrigerated; reheat quickly in a hot pan until steaming hot throughout. Not recommended for freezing — the greens turn watery.
