Celery Braised With Potatoes

2 stalks celery, washed, peeled, cut in large pieces
5 potatoes, peeled, sliced
1 onion, peeled, chopped (or leek or shallots, whichever does not cause a problem for you)
1 cup water
1 cup milk, scalded
1 tablespoon butter
Salt to taste

Boil the celery in salted water until slightly tender (about 10 minutes).
Put the potatoes, onion, milk, and butter in a baking dish.
Drain the celery and add it to the baking dish.
Bake at 350 degrees F for about 40 minutes.
Enjoy!
