Sauces & Rubs

By Alexandra Fleischman | July 9, 2013

A mostarda combines the flavors of mustard with those of candied fruit– and somehow, it works. Like playing with flavors, the grapes retain their bright, sweet flavor, and the mustard seeds and vinegar add a strong kick.

Enjoy this tart, spicy, and sweet condiment with bread and cheese, on top of grilled meat, or panini-pressed into a sandwich. This recipe makes two small jars, and it keeps for about a week.
