This sweet-tart cranberry coulis is the perfect foil for turkey or other poultry and pork. A coulis is a sauce made from pured fruit or vegetables that's cooked down until thick, strained, and then served hot or cold. It's also a great recipe to whip out at christmastime when you want cranberries in the meal, but want to take your meal up a notch from the same old cranberry relish or cranberry sauce.
