Preheat the oven to 300 degrees. Peel the leaves off the red cabbage. Cut the leaves in half, remove the veins, and cut into approximately 2-inch-square pieces. In a large saucepan, melt 4 tbs.

Carve the duck and serve with the braised lettuce and the potato pancakes. Spoon a little of the cooking liquor from the lettuce over the top and tuck in.
