Sweet Potato Casserole

I tried this recipe last year and loved it. It's DELICIOUS!!

Ingredients:
6 lbs sweet potatoes cooked, peeled and mashed
1/2 Tbs. salt
1/2 cup milk
2 cups sugar
4 eggs
4 Tbs melted butter
2 tsp. vanilla
2 cups brown sugar
1 cup flour
1 cup finely cupped pecans
1 stick melted butter
1 tsp. salt

Combine first seven ingredients. Put in a buttered 9x13 casserole dish.
Combine remaining five ingredients for topping. Sprinkle evenly on sweet potato mix.
Bake at 350 until topping is crumbly (about 45-60 min)
If it's too sweet for your taste you can omit some of the sugar.
