"Mignonette" is a sauce made typically with vinegar, pepper, and herbs and served especially with oysters.
Ingredients
1/2 Cup seasoned rice wine vinegar
1/4 Cup fresh lime juice
2 tablespoons minced fresh mint leave
2 tablespoons minced shallot
1/4 Teaspoon red pepper flakes to taste
1/2 Teaspoon Jamaican rum
Directions
Mix ingredients together in a small bowl until combined. Cover and refrigerate until party time.
Note: If seasoned rice wine vinegar is not available, add 1 teaspoon of sugar to regular rice wine vinegar as a substitution -- "seasoned" rice vinegar is sweet.
