It’s August, and that means it’s the dead middle of the dog days of summer. So what do you do with these dog days? You eat cold fish, that’s what. And not just cold fish but raw fish. In a recent “MasterChef” episode, Felix lovingly assigned me a beautiful whole salmon. Salmon is one of those fish that I love to eat raw but can’t stand cooked. In the form of sushi or sashimi, I gobble it up. Even smoked, I’ll throw it on some bread with cheese and herbs.
