Carp with Potato Salad
Peel and finely chop onion. Whisk vinegar with oil and season with sugar, salt and pepper. Scrub potatoes and cook in salted water for about 25 minutes. Drain and let evaporate briefly. Peel potatoes and cut into slices. Place potatoes and onion into a bowl and toss gently with marinade, season to taste.
Rinse and spin dry arugula, cut out hard stalks. Rinse and quarter tomatoes, remove seeds.
Cut carp into serving pieces, score skin gently and season with salt and pepper, dust skin lightly with flour.
