Ingredients: 1 kilo potatoes, 450 grams curly kale, 500 grams minced beef, 2 onions, 1 egg yolk, 2 tablespoons parsley, 4 tablespoons breadcrumbs, salt, pepper, butter, 2 tablespoons vinegar, 200 ml fond, 3 tablespoons syrup, 2 tablespoons raisins, 2 tablespoons cornflour,
Preheat the oven at 90 degrees. Mix 500 grams minced beef with 1 finely chopped onion, 1 egg yolk, 2 tablespoons finely chopped parsley, 4 tablespoons breadcrumbs, salt and pepper. Make 3 or 4 meatballs. Place the meatballs in a ovenproof dish. Place the ovenproof dish in the preheated oven for about 1 1/2 hours. Put the oven the last 8 minutes at 140 degrees so the meatballs are brown.
For the Liegioise sauce you bake 1 finely chopped onion in hot butter. When the onion has softened, add 2 tablespoons vinegar. Bake all a few minutes while stirring. Add 200 ml fond, 3 tablespoons syrup (preferably Liège syrup) and 2 tablespoons raisins. Let it simmer for about a minute or 10. Bind the sauce with 2 tablespoons cornflour (with a little water).
Boil 1 kilo potatoes in water with salt until cooked. Heat 450 grams curly kale with a knob of butter in a separate pot. If the potatoes are cooked mash all together. When it remains dry add a dash of milk. Enjoy!
