How can you improve gravy that is too lemony?

To balance out gravy that is too lemony, you can add a bit of sweetness, such as sugar or honey, which can help counteract the acidity. Additionally, incorporating a richer ingredient like cream or butter can mellow the flavor. If possible, adding more broth or stock can dilute the lemony taste while enhancing the overall flavor. Finally, a pinch of salt can also help to round out the flavors.
