4 large cucumbers
6 medium onions
4 tablespoons butter
4 tablespoons flour
3/4 teaspoon salt
2 cups milk
3/4 cup cheddar cheese, grated*
1/2 cup fine bread crumbs*
Preheat oven to 375° F. Peel cucumbers, and quarter length-wise. Remove the seeds, and then dice the cucumbers into bite-sized chunks. Place in a saucepan and cover with water. Bring to a boil and cook until tender (about 10 – 15 minutes). (Cucumbers are still somewhat firm even when cooked.)
Remove the skins from the onions, and then thinly slice. Place in a saucepan and cover with water. Bring to a boil and cook until tender (about 10 – 15 minutes).
In the meantime, in another pan, using medium heat, melt butter; then stir in the flour, salt, and pepper. Gradually, add the milk while stirring constantly. Continue stirring until the white sauce thickens.
In a large buttered casserole dish, layer the white sauce, cucumbers, and onions. End with a layer of white sauce. Then sprinkle the grated cheese and breadcrumbs on the top. Bake in the oven for 20 – 30 minutes or until hot and bubbly.
*The original hundred-year-old recipe also indicated that nuts or cereal could be used as a topping.
