Before stir-frying anything in any kind of sauce I always marinate it in the sauce. Although veggies do not soak up flavor like meat does, so this may be an unnecessary step if it’s just veggies.
Marinade:
1/4C rice wine (or any cooking sherry)
1/4C Oyster sauce
1/2C Water
Several dashes powdered ginger
(for red meat dishes) generous amount of freshly ground black pepper
(for white meat dishes) several generous dashes white pepper
You can add a squirt of vinegar (for tanginess), soy or fish sauce (for saltiness), dash of sugar (if too bitter), or almost anything else that makes it taste the way you want it to taste. But beware, too much soy sauce & sugar will give you a teriaki flavor.
The measures are very approximate, since I also tend to cook on the fly using the time honored pich-of-this-dash-of-that method. 1/4C seems right for about a half pound of cut up chicken & two handfuls of veggies, but I might just as quickly double the measures if it didn’t look right as I was cooking.
Marinate the meat (or veggies if you like) in this for at least an hour. Over night will give the best (strongest) flavor. Then heat up the wok or large frying pan and add a couple TBSP of oil. Type of oil is your preference, I use peanut oil if I’m making cashew chicken to lend nutty flavor. If you don’t want any flavor from the oil use canola or olive.
Once the oil is hot, lift the meat (veggies) out of the marinade (use a skimmer so the liquid stays where it is for now) and spoon it into the wok. Unless you have a really big wok or frying pan, limit the amount of meat (veggies) that you put into the pan. I suggest no more than 50% of the pan’s surface area should be covered by raw food. You may have noticed that the restaurants use woks big enough to bathe an infant in just to cook a single order. (1) This will give you room to move the food around while cooking, and (2) too much raw food at one time will cool the pan down and you’ll lose the “flash heating” effect that is so important in stir frying.
Veggies stir fry rather quickly, meat takes a minute or two longer depending on how small you cut it prior to marinating.
If you have more raw food than 50% of the pan can accomodate, cook small amounts and move the cooked food into a serving bowl when it’s done. Then bring the pan back to temperature & repeat. Once all the meat/veggies has been cooked, bring the pan back up to temp & pour in the marinade. The pan will cool down with this much liquid, but that’s ok- all we want to do it thicken the sauce & cook any little bits of meat that are left behind in it. The oyster sauce marinade above should thicken fairly quickly, and will thicken a stil more as it cools. Stir briskly to prevent sticking to the bottom (I like to use a compressible whisk because it flattens out nicely to cover the pan’s bottom, but don’t use it on teflon). Other sauces may need a pinch of corn starch to help them thicken.
Pour the thickened sauce over the meat/veggies. Just don’t ask us how to cook rice!
