Saffron adds earthy flavor and a golden hue to the classic French condiment. Serve on fish, over steamed vegetables, as a sandwich spread, or as an appetizer on crostini.
Combine 1 tablespoon warm water and saffron in a medium bowl, and let stand 30 minutes.
Add mayonnaise, vinegar, salt, and garlic to saffron mixture, stirring well with a whisk. Gradually add oil, stirring with a whisk until smooth.
