Wash the plaice fillets and season with a little salt and pepper. Cut the bananas into 4-5 cm long pieces - depending on the size of the plaice fillets - then roll them up in the fillets and secure them with toothpicks. Place the finished rolls in a baking dish.
For the sauce, first chop the spring onions and sauté them in a little oil. Add the curry and then deglaze with the cream. Season with fish stock, pepper, salt, lemon juice and a pinch of sugar. Now thicken with cornstarch.
Then pour the sauce over the rolls and cook in the preheated oven for about 30 minutes at 200 ° C.
