First sin: crowding the pot. Drop in too many pieces at once, and the oil temp crashes to 300°F. Now you’re steaming chicken, not frying it. Work in batches. Be patient. Your craving can wait five minutes.
Second sin: using a too-small pot. Oil needs room to bubble and breathe. A shallow skillet? Disaster. Use a heavy-bottomed Dutch oven or a deep fryer. You want at least 2 inches of oil—enough to submerge the pieces halfway. Flip them once, halfway through, like a tiny, delicious somersault.

The "Knuckle Test" (If You're Brave)
No thermometer? You can guess with a wooden chopstick. Stick it in the oil; if bubbles dance furiously around it, you’re close. Or, use a breadcrumb. If it sizzles within ten seconds, you’re in the zone. But please, please, don’t use your knuckle. That’s for YouTube daredevils, not for us coffee-havers who want to keep our skin.
Another trick: the pop sound. When you add chicken, it should sing a happy, violent sizzle. If it’s silent, it’s too cold. If it’s screaming like a banshee, it’s too hot. You want a proud, steady crackle.
