Ingredients
- ½ cup butter
- 4 scallions (white parts only), minced

- 1 pint half and half
- 8 oz Swiss cheese, shredded
- 1 tablespoon Sherry
- ¼–½ teaspoon ground red pepper

Instructions
- Step 1: Melt the butter in a medium, heavy saucepan over medium heat. Add the minced scallions and chopped parsley, sautéing for 1–2 minutes until fragrant.
- Step 2: Stir in the flour and whisk continuously, cooking for another 1–2 minutes to form a roux.

- Step 6 (optional): For a heartier dish, fill baked puff pastry shells with the crab mornay and serve warm.
