When you velvet chicken, are you supposed to wash off the baking soda?

Question

I am trying to make chicken breast taste better and a technique I found was velveting. However, I'm finding some conflicting information on how to properly do it.

The way I velvet right now is I cut up my raw chicken breast (800-1000g), then add about 10g of baking soda, then add a bit of water, just enough to submerge the chicken breast pieces. Then I leave it on my countertop for like 15-20 minutes. Once that's done, I drain and squeeze the chicken pieces a bit, then I coat with some sesame oil and let it marinate for a bit more.

My question is, is this technique correct? Am I supposed to just mix chicken with baking soda and nothing else, no water? Am I supposed to wash off the baking soda once it's done? What if I want to add spices, at what step does that come in?

Answer 1

There is some controversy about the ingredients for velveting, but the idea behind the Chinese technique, is that meat (chicken, pork, or fish) is marinated, then given a hot oil blanch, before being stir fried. The purpose of the technique is create a smooth and silky texture.

Baking soda is indeed mentioned, but less commonly than egg white and cornstarch. Some, leave those three ingredients out altogether, and simply marinate in oil and still call the technique "velveting." Most common seems to be a combination of egg white, cornstarch, and Chinese cooking wine.

The marinade is not washed off before use. Here is a good explanation. I haven't looked for any science on the topic, but it would be interesting to see if it has been studied. If I find anything, I will update.

Answer 2

One teaspoon or one tablespoon of baking soda per ounce of protein will achieve the same result. A teaspoon will take longer, and a tablespoon will leave behind un-reacted baking soda. Baking soda doesn't taste particularly good in large amounts so it's wise to wash it out but if you use the smallest amount to get the job done you don't need to.

Also take into account the thickness. If your solution is not strong enough you will not penetrate to the center in a reasonable time.

Third, unrated baking soda will react with the amino acids and proteins in the cooking process. So it can be a good idea to neutralize the baking soda with cream of tartar, vinegar, or lemon juice. I like cream of tartar for a natural flavor.

Answer 3

This is a complete guess, as I do not eat chicken. But I used to.

If you cover chicken strips in sodium bicarbonate (or soak them in a solution) you are marinading it in an alkaline solution. My guess is that if you do this long enough, the first millimetre or so of the chicken will break down a little and absorb some of that bicarbonate.

If you then stir fry it at high temperature, especially with something acidic, such as lime (the fruit juice!), then the acid and alkali will react by foaming which will further break down and soften the chicken surface.

It would need a long marinade and the other acid ingredient to work, I guess (though heat does activate baking soda) but I would think that without a high heat the chicken won’t cook fast enough for the effect to be noticeable.

So the blanching in hot oil as mentioned above makes some sense.

On the other hand, why bother? Instead use great ingredients - fresh free range organic poultry cooked just beyond pink is out of this world and doesn’t need to be treated with anything.

The best stir fry I have had have all been home cooked, with minimum ingredients - maybe some fresh ginger and garlic with pak choi..
