Infuse the milk: In a small saucepan, gently warm the milk with the bay leaf. Let it steep for a few minutes, then remove the bay leaf and set the milk aside.
Make the sauce: Sauté the chopped onion in butter until soft but not browned, for 2-3 minutes. Stir in the flour and cook for a minute, then gradually add the infused milk, whisking constantly to form a smooth sauce.Off the heat, stir in the cream, grated cheese, mustard, pepper, nutmeg, and ground cloves.
Assemble and bake: Butter a baking dish, add the cauliflower florets and pour the sauce over the florets. Top with extra cheese and breadcrumbs. Bake at 200°C for 15-20 minutes, until golden and bubbling. Serve hot.
