Heat oven to 350 degrees.
In a large mixing bowl, combine mustard, garlic, thyme, cinnamon, a pinch of salt and ½ teaspoon black pepper.
Place bread crumbs in another large bowl.
Working in batches, coat chicken quarters on all sides with mustard mixture.
Shake off excess mustard, then coat completely with bread crumbs.
Arrange in a single layer in a large, shallow baking pan.
Dust the chicken with paprika and scatter butter pieces on top.
Bake until crust is deep golden brown and crispy, about 2 hours.
