Method
Boil the potatoes in salted water until tender, drain, and mash with the egg yolk, a knob of butter, a splash of milk, salt and nutmeg.
Timer · 20 min20:00Put the witloof in a pan with a knob of butter and a splash of water and bring to the boil. Season with salt, pepper and nutmeg, cover with a round of baking paper and cook gently until tender and lightly coloured.
Why Escoffier braises witloof in butter, water, salt and lemon for 30–35 minutes after boiling, and warns never to blanch it in water first: it would turn watery and bitter.
Timer · 30 min30:00Drain the witloof very well in a sieve, keeping the cooking liquid. Roll each head in a slice of ham.
Why Water left in the witloof seeps into the sauce in the oven and can make it split.
Melt the 40 g butter, stir in the flour to a roux, then whisk in the milk. Bring to the boil and melt in the cheeses. Season with pepper, salt, nutmeg, lemon and mustard, and stir in the witloof cooking liquid.
Timer · 10 min10:00Heat the oven to 200 °C with the grill. Lay the rolls in the dish, cover with the sauce, scatter the extra Emmental over and bake 25 minutes until golden. Serve with the mash.

To drink & serve with
- Stoemp
Mash is the usual partner; a stoemp works too.
Substitutions
- Ham → Leave it out for a vegetarian gratin (Escoffier's endives à la Mornay are made without ham).
- Plain flour (gluten-free) → Thicken the milk with cornflour slaked in cold milk.
Common mistakes
- Not draining the witloof well: the sauce splits and the dish is watery.
- Blanching the witloof in boiling water: it turns bitter and soggy.
Storage & reheating
The assembled dish can be cooled, refrigerated and baked the next day, or frozen. Refrigerated leftovers keep 2 days; reheat until piping hot.
Safety
Contains gluten, milk, egg (in the mash) and mustard.

Brussels chicory
Witloof, chicon in Brussels and Wallonia and Belgian endive in English, is a forced chicory with pale, tightly closed leaves. Escoffier already called it chicorée de Bruxelles in 1903 and gave it a section of its own, including endives baked under Mornay (cheese) sauce. Rolled in ham and gratinéed, it became a Belgian family dish; Jeroen Meus's version is the one given here.
Braise, drain, gratinate
Escoffier's rule for witloof is to braise it directly in butter, a little water, lemon and salt, never blanching it first, so that it stays white. Meus braises it gently under paper until it colours lightly. The essential step is draining: the heads hold a lot of liquid, which would thin the cheese sauce in the oven.
