Instead of—or in addition to—a classic gravy, consider this bright, intensely flavorful South American sauce. We’ve adapted the recipe from one in Rich Table by Sarah and Evan Rich.

In a small bowl, combine finely chopped shallot with vinegar. Let sit at room temperature 30 minutes; strain. Reserve shallot and vinegar separately.
Whirl coarsely chopped shallot in a food processor with remaining ingredients (except green beans) to make a paste. Pour into a bowl.
Stir in vinegared shallots and beans. Season with salt and reserved vinegar to make sauce bright and balanced.
