Emma’s Cod and Potatoes

Once, for a special occasion, I produced potatoes Anna—a dish in which potatoes are thinly sliced, drenched in butter, and roasted until golden, the ultimate in crisp potato dishes—for my daughter Emma. This was a fatal error, because potatoes Anna are a pain to make, contain about a week’s allotment of butter, and were forever in demand thereafter. So I set about shortcutting the process, creating something approaching an entire meal. I cut back on the butter (when attacks of conscience strike, I substitute olive oil) and enlisted the broiler to speed the browning process. I figured that it would be just as easy to broil something on top of the potatoes during the last few minutes of cooking and, after a few tries, I found a thick fillet of fish to be ideal. The result is this simple weeknight dish that I now make routinely and one that even impresses guests.
