Kachkeis, whose name means "cooked cheese", is a much-loved Luxembourgish specialty: a smooth, soft, spreadable cheese made by gently melting down a matured curd until it turns glossy and pourable, often with a hint of caraway stirred in. It sets to a silky, savoury spread quite unlike a firm sliceable cheese.
It is thoroughly everyday food, the kind of thing Luxembourgers grow up on and keep in the fridge. Spread generously on fresh bread, frequently with a swipe of mustard to cut its richness, it makes a simple, comforting breakfast, snack, or light supper.
Homely, tangy, and unpretentious, kachkeis is one of those small national foods that outsiders rarely meet but that locals hold real affection for. In a country proud of its distinct identity, even the cheese on the morning bread is quietly its own.

Ingredients
US
Metric
Serves 4
2 cups (about 1 lb) dry curd cheese or well-drained quark, aged 2 to 3 days
1/2 tsp baking soda
2 tbsp butter
1/4 cup milk
1 tsp caraway seeds
1/2 tsp salt
4 thick slices fresh bread, to serve
to taste mustard, to serve
Instructions
1
A few days ahead, leave the drained curd loosely covered at cool room temperature to ripen and soften. It should smell sharp and turn slightly translucent at the edges.
✎ Chef’s note
This ripening is what lets the curd melt smoothly instead of staying grainy. Well-aged supermarket quark, drained hard, works if you cannot ripen your own.
2
Crumble the ripened curd into a bowl and mix through the baking soda. Let it stand 30 minutes.
3
Melt the butter in a heavy saucepan over low heat, then add the curd.
4
Stir constantly over low heat. After a few minutes the curd will suddenly collapse and turn glossy and stringy.
5
Whisk in the milk a little at a time to loosen it to a thick, pourable cream, then stir in the caraway and salt.
6
Cook gently 2 to 3 minutes more until completely smooth, with no lumps remaining.
7
Pour into a shallow dish and cool. It firms as it cools into a soft, spreadable cheese; refrigerate to set fully.
8
Spread thickly on fresh bread, add a smear of mustard, and serve.

📍
Luxembourg City. Luxembourg City feasts on judd mat gaardebounen, smoked pork collar with broad beans, treated as the national dish. Its kitchen borrows freely from France and Germany, in river fish, black pudding with apple, and quetsch plum tart.
🗺️
Luxembourg. Judd mat Gaardebounen is tied to one village, Gostingen, whose inhabitants are nicknamed Bounepatscherten, bean-madmen. The smoked pork collar is soaked, then simmered with leeks, carrots, celery and cloves, often with Moselle wine, and served with broad beans. The word judd has no settled etymology, though one theory derives it from the Spanish judia, meaning bean.
🌍
Europe. A surprising amount of European cooking is under five hundred years old. Tomatoes, potatoes, peppers, maize, beans and chocolate all crossed from the Americas after 1492, and none of them was trusted quickly: the potato took most of the eighteenth century to be accepted as food rather than animal fodder across much of the north.
The story behind this dish is up top, worth a read while the pot works.
