Zest one of the oranges and set aside both zest and orange. With a knife, cut away the peel and pith from all oranges. Coarsely chop oranges. Place cranberries, chopped oranges, orange zest and sugar into a food processor and pulse until coarsely chopped. Let sit at least an hour at room temperature before serving.

Fact: Zest is the outermost part of the orange skin, not the white pith (which is bitter!). A vegetable peeler, pairing knife or citrus zester works great for this task.
