　　1 1/2 tablespoons freshly grated lemon zest

　　1/2 cup fresh lemon juice

　　6 ounces salmon roe

　　3 tablespoons chopped fresh dill sprigs

　　

Step 1

Fill a 6-quart kettle three fourths full with salted water and bring to a boil for pasta.

　　

Step 2

In a deep 12-inch skillet heat butter and cream over moderately low heat until butter is melted. Stir in zest, lemon juice, and pepper to taste. Remove skillet from heat and cover to keep sauce warm.

　　

Step 3
