Velveting
Velveting is a Chinese technique for keeping meat tender in high-heat cooking. Thin slices of chicken, pork, beef or shrimp are coated in a light marinade, usually cornstarch with egg white, rice wine or a pinch of baking soda, then briefly pre-cooked in water or oil before going into the stir-fry. The result is the soft, silky, juicy texture of good restaurant stir-fries.
Why it works
Velveting attacks toughness in three ways.
A starch shield. Cornstarch granules absorb water from the marinade. When they hit heat, they gelatinize between about 62 and 72 °C (145–160 °F), forming a soft gel that coats each slice. That layer insulates the meat from the wok's fierce heat and holds juices in.
A protein coat. Egg white proteins set around the meat as they cook, reinforcing the coating. The coating also helps sauce cling.
An alkaline boost. Baking soda raises the meat's pH. At higher pH, muscle proteins carry more negative charge and push each other apart, so they hold more water and can't bond as tightly when they denature in the heat. That's why baking soda makes even lean flank steak tender.
Salt and soy sauce help too: they dissolve some muscle proteins on the surface, which then hold onto moisture.
Basic ratios
For 450 g (1 lb) of meat, sliced 3–5 mm (⅛–¼ in) thick against the grain:
| Ingredient | Amount | Role |
|---|---|---|
| Cornstarch | 1 tbsp (8 g) | Protective gel coating |
| Egg white (optional) | 1 large | Protein coat, silkier texture |
| Shaoxing wine or dry sherry | 1 tbsp (15 ml) | Flavour, moisture |
| Soy sauce or salt | 1 tsp soy or ½ tsp salt | Seasoning, water retention |
| Neutral oil | 1–2 tsp | Separates slices during cooking |
| Baking soda (beef, pork) | ¼–½ tsp | Raises pH for tenderness |
Mix, then rest 15–30 minutes in the fridge. Longer is fine for cornstarch-only marinades; with baking soda, more than an hour or two can make meat spongy.
Pre-cooking options
- Water velveting: Drop slices into barely simmering water with a spoonful of oil, separate gently, and lift out as soon as they turn opaque, 30–90 seconds.
- Oil velveting: Fry in 2–3 cm of oil at about 120–150 °C / 250–300 °F for under a minute, without browning. Drain well.
- Direct stir-fry: Skip pre-cooking and sear the coated meat in batches. You get more browning, slightly less silk.
Common mistakes
- Too much baking soda. It tastes soapy and makes meat mushy. Measure it.
- Cutting with the grain. Long muscle fibres stay chewy no matter how you marinate. Slice across them.
- Boiling hard. Violent water strips the coating. Keep it at a lazy simmer.
- Overcooking after velveting. The coating buys you time, not immunity. Add velveted meat back at the end and toss just until hot.

Questions
What is the difference between water velveting and oil velveting?
Oil velveting briefly passes coated meat through oil at about 120–150 °C / 250–300 °F, the classic restaurant method. Water velveting simmers it in barely bubbling water with a little oil for 30–90 seconds. Water is easier and less greasy at home; oil gives a slightly richer, silkier coating.
How much baking soda do you use to velvet beef?
About ½ teaspoon (2–3 g) per 450 g (1 lb) of sliced beef, mixed in for 15–30 minutes. If you use more, up to 1 teaspoon, rinse the meat and pat it dry before adding the rest of the marinade, or it will taste soapy.
Can you velvet shrimp?
Yes. A light coating of egg white, cornstarch and salt for 15–30 minutes gives shrimp a plump, snappy texture. Skip baking soda or use only a pinch, since shrimp are already delicate.
Is velveted chicken cooked after blanching?
Not necessarily. Thin slices often turn opaque in a minute but should finish in the stir-fry. Chicken must reach 74 °C / 165 °F; thin pieces get there quickly in a hot wok.
