- In separate medium saucepans, cook the cabbage and the potatoes in salted boiling water for 12-15 minutes, or until tender. Drain the cabbage and chop. Drain the potatoes and mash.
- In a large saucepan, combine the leeks and milk. Bring to a simmer and cook for 8-10 minutes, or until the leeks are tender.
- Add potatoes, salt, and pepper to the leek mixture and stir over low heat until well-mixed. Add the cabbage and butter and stir again.
- Top with a few more slices of butter, or a sprinkling of parsley, if desired. Serve immediately.
- Note: For a version using turnips, substitute 1 pound turnips, peeled and cut into 1-inch pieces, for the cabbage. Swap 1 cup buttermilk for the milk. Combine the mashed potatoes and mashed turnips. Stir in the buttermilk. Add salt and pepper and sprinkle with minced fresh chives.
