Add heavy cream and return to a simmer (this will only take about 30 seconds). Remove the pan from the heat. Begin adding pieces of cold butter and whisking. As the added pieces melt, add a few more. If the sauce cools and the butter has stopped (or slowed) melting, return the pan to heat for 10-15 seconds - just long enough to begin melting the butter again - then remove from the heat and continue adding butter and whisking. Once the butter has incorporated, remove the garlic clove from the sauce. Taste the sauce and add a pinch of salt, if needed.

Serve creamy lemon butter sauce over baked fish, seared salmon, colossal shrimp or grilled asparagus.
