Butterfly Bakery made this spicy pickle mustard in collaboration with the alternative rock band Guster. Gustard is a garlic, dill, jalapeno and cucumber mustard that is fabulous on sausage, burgers and pretzels. A portion of all proceeds are donated to Zeno Mountain Farm (The Mission of ZMF is to support lifelong friendships and opportunities for people with and without disabilities and other marginalized communities). You can enjoy this delicious mustard and support a great cause with every mouthful.
