I heat the olive oil in a cast iron roaster and fry the pieces of meat in it. After that, finely chopped onions are added and stewed until translucent. I deglaze with semi-dry white wine.
Heat up the sauce again and cook it a little, season it and fill it with a spoon into clean screw jars and seal them. This way the ragout will keep in the fridge for at least a week.
