Lynne's Sweet Potato Casserole

1 can sweet yams(40oz.) I buy the Tops brand

3 medium apples

1 cup flour

1/2 cup sugar

1/4 tsp. salt

1/2 tsp. cinnamon

1 egg

butter pats for the top

I drain the juice from the potatoes and put it aside. Put the potatoes in a baking dish. Pare and toss the apples with the potatoes. In a separate bowl mix the flour, sugar, salt and cinnamon. Make a well in the flour mixture and add the egg. Beat the egg and mix the ingredients at the same time. Spread over the potatoes. I toss it a little bit. Now pour some of the juice over the top to moisten some of the topping. Lastly place butter pats over the top. I use as little as possible, about 6 thin pats should do it. Bake at 375 for about 45 mins. If you're in a hurry you can microwave for about 15 mins. Keep an eye on it so it doesn't overflow.
