You’ve seen those posts: “Cook until flakes easily with a fork.” That’s a trap. By the time it flakes, it’s already dry. The real test is opacity. Look at the side of the fillet. When it’s just barely opaque in the thickest part, and slightly translucent in the center—that’s your moment.
Use a thermometer. It’s not fancy. It’s a cheat code. Stick it in the thickest part, away from the bone. If you don’t have one, you’re an explorer without a map. You’ll probably find a desert.
The “Residual Heat” Hack
Here’s a fun party trick: take the salmon off the heat at 120°F. Yes, you read that. The internal temperature will climb another 5-8°F as it rests. That’s called “carryover cooking.” It’s like the salmon is still deciding if it’s done.
Let it rest for 3 minutes on the counter. It’s not a nap. It’s a strategy. During that time, the juices redistribute. You get a perfect, moist flake. Not a crumbly mess.
