This is a really old recipe. Something that my mom always made and her mom before her. Simple and delicious.

1 can of creamed corn (about 2 cups)
Baked ham (I like to put in about 2 layers at least, sliced into pieces about 1/3 inch thick)
4 medium potatoes, peeled and cut into slices, again about 1/3 inch thick
1 medium onion, peeled and thinly sliced
6 ounces of milk, scalded (heat just until bubbles appear around the edges of the milk in the pan)
salt and black pepper to taste
2 tablespoons flour
2 tablespoons butter, cut into bits

Preheat the oven to 350 degrees. Butter a 9 x 13 casserole dish.

Layer everything in the casserole dish, beginning with a spoonful of the corn on the bottom, then add 1/3 of the potatoes, half of the onion, half the flour, 1/3 of the butter, some salt and pepper to taste (remember ham is salty so don't use too much) some more creamed corn and half of the ham.

Do another layer with 1/3 of the potatoes, the remaining onion, the remaining flour, 1/3 more of the butter, salt and pepper and the remainder of the ham, and half of the remaining corn. Top with a final layer of potatoes, and the rest of the corn. Season lightly and dot with the remaining butter.

Pour in the milk. You may not need all of it. You just want to barely see it through the top, it should only fill the dish about 2/3 full. Cover with a lid and bake for about 45 minutes. Uncover and bake for a further 15 minutes, or until the potatoes are tender and the casserole is golden brown. Serve hot.
