  • Yield: 8 servings. (See Tip 5)


  1. Feel free to use whatever pasta you have on hand. Just make sure to cook it to the al dente stage.
  2. For a richer dish, you can use half and half in place of the milk.
  3. The dry sherry adds a subtle flavor. If desired, you can either omit the sherry, or use white wine in place of it.
  4. To toast the almond slices, bake them at 350°F for 8 to 10 minutes. Watch carefully to ensure that they don't burn.
  5. This makes excellent leftovers, and freezes beautifully.
