This recipe is so weird I really don't know what to say about it. I have the feeling it must have come from some Citrus Commission because it specifies Florida grapefruit. I don't see how anyone else would think of combining grapefruit, cabbage and sausage. I guess it is possible that the acid from the grapefruit juice gives the cabbage a kraut-like flavor but I am not about to try it.
Grapefruit Sausage Kraut
1 tablespoon salad oil
1 onion, chopped
1 1/2 pounds sweet sausage
1 green cabbage, shredded
2 teaspoons sugar
2 teaspoon dill seed
1/2 teaspoon salt
1 1/2 cups Florida grapefruit juice
2 Florida grapefruit, sectioned
Heat oil in large saucepan or Dutch oven. Add onion and cook until tender, but not brown. Cut sausage into 1-inch pieces. Add to pan and cook until browned on all sides. Add shredded cabbage; cover and cook until cabbage begins to wilt, about 10 minutes. Remove cover, stir and continue to cook over low heat, uncovered, 20 minutes; stir occasionally. Add grapefruit sections and heat. Makes 6 servings.
