Grandma's braised beef and onions (hachee)

Perfect winter comfort food.

What you need (approx. 5-6 servings):
750g beefsteak, cut into cubes
1kg onions, cut in half and sliced
100g butter or margerine
80g flour
2 bay leaves
some cloves
vinegar

Melt the butter in a large pan. Add the onion and beef, and pan fry until the onion has softened and the beef has browned. Add sufficient water to cover the beef and add the bay leaves, cloves and a splash of vinegar.
Simmer for approx. 2 hrs.
In a dry pan, cook the flour whilst continually stirring, until it's nicely browned (don't let it burn!). Add some water to make a sauce and add this to the stew. Stir until mixed evenly and the liquid has thickened.
Serve with your choice of (mashed) potatoes and cooked veggies.
