Step 1

Stir the cream and the lemon juice in a 1-quart saucepan over medium heat to blend. Add the butter and stir gently until the butter melts. After the butter has melted, lower the heat to medium-low and whisk constantly until the mixture begins to thicken, about 8 minutes.

Step 2

Stir in the grated Parmesan cheese and nutmeg, and continue to stir or whisk until the cheese has melted and the sauce has thickened even more, about 3 minutes.

Step 3

Remove from the heat and toss with cooked pasta or add to cooked chicken or shrimp.Pro Tip: The sauce will continue to thicken as it sits. Taste and add ⅛ teaspoon of salt if necessary.
