7 cups cauliflower, cut into florets   1.1 kg
1/4 cup margarine non-hydrogenated   55 g
2 tbsp white flour (all purpose)   16 g
2 cups milk, partly skimmed, 2%   500 mL
3 tbsp horseradish   45 mL
2 tsp apple cider vinegar   10 mL
2 tsp Dijon mustard   10 mL
60 g Emmenthal cheese, grated   3/4 cup
1 pinch salt [optional]   0.1 g
  ground pepper to taste    


  1. Preheat the oven to 190°C/375°F.
  2. Prepare the cauliflower : cut into equal-size florets, then blanch them in a pot of salted boiling water until crisp-tender, about 6 min. Drain and transfer the florets to a baking dish.
  3. While the cauliflower is cooking, heat the margarine in a saucepan over medium heat. Add the flour and stir 2 min, paying attention not to let it burn. Gradually whisk in the milk, then cook until the sauce boils and thickens, whisking constantly, 3-4 min. Mix in the horseradish, vinegar, mustard, and grated cheese. Season with salt and pepper. Pour the sauce over the cauliflower and mix to coat.
  4. Bake in the middle of the oven until the cauliflower is golden-brown on top, about 25 min. For a nice crust, turn on the top broiler for the last 2 minutes. Serve hot.


The cauliflower and sauce can be prepared a couple days ahead, chilled in the refrigerator, then baked just before serving.
