There’s no shame in making a mistake; we all do. And while it may feel a bit wasteful to throw food in the trash, tossing out burned garlic, charred nuts, or smoking oil is the right thing to do. Start again fresh (if you have extras of the ingredients). Of course, there is a no-turning-back point, too. If you’ve overcooked a chicken because you didn’t use a meat thermometer, you’re bound to serve an overcooked chicken. At that point, the best practice is to 'fess up, apologize, pass the wine, and move on.
