Tender cauliflower florets baked under a rich, velvety nutmeg-scented béchamel cheese sauce until bubbling and golden brown.
Preheat oven to 200°C. Arrange blanched, drained cauliflower florets in a buttered baking dish.
Melt butter, whisk in flour for 2 minutes, then slowly whisk in milk and vegetable water. Simmer until thick, seasoning with nutmeg, salt, and pepper.
Pour the hot sauce evenly over the cauliflower florets. Sprinkle grated cheese generously over the top.
Bake for 20-25 minutes until the cheese is bubbling vigorously with a deep golden-brown crust. Serve warm.
