Oh, you fancy? For grilled corn, you’re looking for char marks and that smoky smell that makes neighbors jealous. The kernels should start to blister and turn a little brown. Don’t be shy—let it blacken in spots. That’s flavor.
For oven-roasted corn (in the husk, 350°F for 30 minutes), the husk will turn brown and the silk will smell like toasted hay. The kernels will be steam-cooked to perfection. Pull one kernel off and see if it releases easily from the cob. If it does, you’re golden.

The Ultimate Test: Just Eat a Kernel
Stop overthinking. The best test is the taste test. Cut a single kernel off the cob if you have to. Cool it down, pop it in your mouth, and chew. Is it crisp but tender? Sweet and juicy? You’re done. Is it crunchy and grassy? Keep boiling.
Is it mushy and bland? You’ve cooked it to death. It happens. Pour butter on it anyway and call it “rustic.” We’ve all been there.
