Many woks also come with a lid, handy for slow braising as it prevents the liquid from evaporating. But for a stir-fry, you want to cook the dish quickly in a small amount of oil with the lid off so the steam escapes.
The key to making a really good stir-fry is using a very high cooking temperature so the food will cook quickly. Since stir-frying involves high heat, it's important to choose an oil that has a high smoke point. If you don't, the oil will burn and the whole dish will be ruined.
Start with the hard vegetables like carrots and broccoli. Stir and scoop vegetables to the side to make room for more. Then add the softer vegetables, like sliced mushrooms and zucchini. Pour in some stock or water and always keep the veggies moving in the pan.
You'll end up with a mixture of food where some is overcooked and either burnt or soggy, and some that's undercooked, or even raw. You also risk overcrowding the wok when you add everything at once.
The best oils for stir frys are the oils with the higher smoke points. These tend to be the “thinner” oils such as peanut, grapeseed or canola.
If you add too many ingredients at once, they will overlap and steam, rather than sauté, making them rubbery or soggy. "Cook each ingredient separately," advises Martinez. Not only does this ensure that you won't pile too much in the pan at once, but it will also account for different cooking times.
Cut Thin Slices
The thinner the beef, the more tender it will taste and the less chewy it will be. Thicker strips require longer cooking times, which usually means the outside is overcooked by the time the inside is cooked.
Can I add water to a stir fry? Yes, if you want to steam the vegetables. Sometimes I will add 2 tablespoons of water or broth after adding the vegetables. I put a lid on the pan and allow the ingredients to steam for 2 to 5 minutes depending on how raw the vegetables are and how much food there is.
Stir-fry onions first, then add hard vegetables such as carrot and broccoli. Quick-cooking vegetables, such as snow peas, leafy greens and bean sprouts, should be added towards the end of cooking.
Meat first, then vegetables – If you want meat or seafood in your stir fry, cook it first then scoop it out onto a separate plate before cooking the vegetables. You'll add the meat back in at the end. 5. Don't crowd the pan – If you have too much in your pan, the vegetables will steam instead of staying crisp.
Aromatic ingredients like garlic, ginger, green onions, chilies and spices. These ingredients are typically added to the oil first to infuse it with flavor. You won't need much; a few teaspoons to a tablespoon of total aromatic ingredients per person adds a serious amount of flavor.
Oil: Although you can use almost any kind of cooking oil while you master how to make stir-fry, peanut oil is ideal. It can reach a higher temperature than other oils before it starts smoking. (If you have a nut allergy, other high smoke-point oils such as canola or avocado oil are great alternatives.)
While 2 tablespoons of oil per serving is a solid guideline for stir fry cooking, some ingredients can require a lot more or sometimes a lot less.
Soy sauce, sesame oil, a bit of vinegar, or store-bought stir-fry sauces are easy to add to the dish and most stir-fry recipes will include a suggested mixture of liquid. If you don't really have a sauce planned, a bit of bottled soy sauce and some diced garlic or ginger will make a nice basic stir-fry sauce.
Cornstarch! In his book How to Cook Everything Vegetarian, Mark Bittman recommends mixing 1-2 tablespoons of cornstarch with the same amount of water, and tossing this into the stir fry just when it's almost done. It thickens in seconds, picking up the flavors of everything already in the dish and coating evenly.
Eating a stir fry may be a healthy option, but cooking it could be bad for your health because it shoots microscopic particles of fat into the air, which could be hazardous if inhaled, scientists have warned.
Stir-fry vegetables according to density, with the densest vegetables being stir-fried first and for the longest time. Denser vegetables such as broccoli, carrots, and eggplant require more cooking time than green leafy vegetables such as bok choy.
Regular frying temperature is 350F. Stir frying temperature is at least 450F — it can be higher but that's the minimum. If you stir fry using oil with a smoking point below 450F, not only will the food taste bad, it will also be a health hazard.
Heat the oil in a large frying pan or wok, then fry the chilli and garlic for 1 min. Add the veg and toss to coat in the oil. Fry for 2-3 mins, then add the soy and chilli sauce, mixing well. Cook for 2-3 mins more until the veg are tender.
