Moules-frites

Method

1. 1 Wash the mussels, remove the antennae, and discard any that have open mouths that don't close when tapped.
2. 2 Cut the potatoes into 1 cm strips, soak them in water for 15 minutes, fry them once at 150 degrees for 6 minutes, then let them cool.
3. 3 Sauté the onions and celery in butter for 6 minutes, then pour in the beer and bring to a boil.
4. 4 Pour the mussels into the pot, cover and shake the pot, steam for exactly 5 minutes; the mussels are cooked when they open their shells, steaming longer will shrink the meat.
5. 5 Fry the potatoes a second time at 190 degrees for 3 minutes until golden brown and crispy.
6. 6 Sprinkle parsley and pepper over the mussels, and serve with fries and mayonnaise.
