Receipe?
Slice some potatoes and part boil, drain and once cooked add to a baking dish
Season with lots of salt and pepper and a little butter
At the same time fry some pancetta or the like and some onion then add to the potatoes in the baking dish
Season again and perhaps add a glug of dry white wine
Finally add a large slab or 2 of reblochon cheese, covering all of the potatoes.
Throw in the oven for about 30 mins until the cheese is crisp and bubbling
Serve with a green salad dressed with a mustard dressing and ideally some charcuterie.
Absolute filth.
