Louisiana-Style Black Cod

Toss potatoes on a baking sheet with a drizzle of oil, salt, and pepper.

Roast on top rack until golden brown and crispy, 20-25 minutes.

Meanwhile, in a small bowl, combine mayonnaise, mustard, chopped scallion whites, one packet sour cream (two packets for 4 servings), 1 tsp vinegar (2 tsp for 4), and a pinch of chili to taste. (You’ll use the rest of the sour cream and vinegar later.) Season with salt and pepper. Set aside.

To bowl with carrot, add cabbage, two packets sour cream (four packets for 4 servings), remaining vinegar, 2 TBSP scallion greens (4 TBSP for 4), and 1½ tsp sugar (3 tsp for 4). (You’ll use the rest of the sour cream in the next step.)

Season with a big pinch of salt and pepper; toss to combine.

Halve tilapia fillets* lengthwise. (You’ll have a larger piece and a smaller piece.) Pat dry with paper towels.

In a shallow dish, combine Old Bay Seasoning, remaining sour cream, and 1 TBSP water (2 TBSP for 4 servings).

On a plate, combine panko and cornstarch.

Dip each fillet into sour cream mixture, then press into panko mixture, coating all over.

Heat a ⅓-inch layer of oil in a large, preferably nonstick, pan over medium-high heat. Once oil is hot enough that a pinch of panko mixture sizzles when added to pan, add tilapia and cook until crust is golden and fish is cooked through, 2-3 minutes per side (the smaller pieces will cook faster). (For 4 servings, fry fish in batches.)

Transfer to a paper-towel-lined plate.
