- In a small saucepan over medium-low heat, reduce wine to almost dry along with shallots and garlic, about 5 minutes.
- Add cream, chopped cauliflower, lemon zest and a pinch of pepper. Cook covered on low for about 15 minutes, until cauliflower softens. There should be 15 mL (1 tbsp.) of cream left in saucepan.

- Season with salt and pepper, and add a pinch of pepper if desired. Taste and adjust seasoning as required.
- Pat seafood dry. Divide purée in two shallow oven-proof bowls, add scallops and shrimp, and sprinkle with cheese and breadcrumbs.
- Bake for 8 minutes; then broil for 2 to 3 minutes, until tops are nicely browned. Let stand 5 minutes before serving.
