In a medium mixing bowl, combine 1 cup of sour cream and ½ cup of mayonnaise. Use a spatula or whisk to blend these two creamy bases together until fully mixed and smooth.

Finely mince 3 cloves of fresh garlic and stir into the creamy mixture until evenly distributed.

Sprinkle in ¼ cup of grated Parmesan cheese, followed by a pinch of salt and freshly cracked pepper. Fold into the mixture until well incorporated.

Cover the bowl tightly with plastic wrap and chill in the refrigerator for at least 30 minutes.

After chilling, stir gently to recombine any ingredients before serving as a topping or dip.
