Endive au Jambon Gratinée

Endives au jambon (endives/chicory wrapped in ham and baked in béchamel) is the Nord's most beloved everyday gratin — a dish that appears on virtually every family table at least once a week during the cold months, and that defines the northern French approach to vegetable cookery: substantial, warming, sauce-enriched, and designed to sustain. The Belgian endive (Cichorium intybus, called chicon in the Nord, endive in Paris, witloof in Flemish) was developed in Brussels in the 1850s and became the signature vegetable of the Nord, where it is grown in dark forcing rooms (to keep it white and mild) in vast quantities. The technique: trim and halve 8 endives lengthwise, braise in a covered pan with 30g butter, a teaspoon of sugar, a squeeze of lemon juice, salt, and 3 tablespoons of water over low heat for 30-40 minutes until completely tender and slightly caramelized. The sugar and lemon counteract the endive's inherent bitterness — this braising step is critical and cannot be skipped. Drain the endives thoroughly (excess liquid ruins the gratin). Wrap each braised endive half in a slice of good ham (jambon blanc/jambon de Paris). Arrange in a buttered gratin dish. Make a béchamel: 50g butter, 50g flour, 500ml milk, seasoned with salt, white pepper, and nutmeg. Optionally, stir 100g grated Gruyère or Comté into the béchamel for extra richness. Pour the béchamel over the ham-wrapped endives, scatter with more grated cheese, and bake at 200°C for 25-30 minutes until bubbling and deeply golden. The gratin should be served in its dish — each portion scooped out to include the caramelized endive, the salty ham, the creamy béchamel, and the golden cheese crust.
