The key to great wok cooking is achieving "wok hei" - that smoky, charred flavor that makes restaurant stir-fries so distinctive. Here's how to get it at home: **Preheat your wok until smoking** - this takes 2-3 minutes on high heat. A properly heated wok will cause a drop of water to evaporate instantly. **Work in small batches** - overcrowding drops the temperature and steams your food instead of searing it. Cook proteins first, set aside, then vegetables. **Keep things moving** - constantly toss and flip ingredients to prevent burning while ensuring even heat distribution. **Use the right oil** - peanut oil, avocado oil, or rice bran oil can handle the high temperatures without smoking.
