Put some butter in a pan for frying. Finely dice the onion and sauté in it until translucent. Halve the meat sausage lengthways and then cut into thin slices. Add to the onions and fry until brown. Add the corn. Mix with the cream and add enough tomato ketchup until it turns a light orange-red color. Season to taste with the spices and simmer for about 10 minutes.
