Cut the pork neck into 4 equally sized slices. Brush the meat generously on both sides with mustard and place in a bowl. Roughly chop the onions and pour over the meat. Sprinkle plenty of salt and pepper over the meat and fill up with the beer.
Let it steep for 2 - 3 hours.
Then there are three cooking options:
- Bake in the oven at 180 degrees for 45 minutes.
- Wrap in aluminum foil and place in the hot grill ash for 30 minutes.
- Sear the pieces of meat on both sides on the charcoal grill.
