Sweet Potato Casserole

We had this for the first time in Taiwan during Thanksgiving in the home of an ex-pat South Carolinian. I’ve reduced the sugar and now, it’s on our table every year during the holidays.

3 cups mashed, cooked sweet potato
½ cup sugar
½ teaspoon salt
2 eggs
½ cup milk
3 Tablespoons butter
1 teaspoon vanilla
 
Mix all ingredients; pour into a greased baking dish. Cover with the following topping:
 
Topping:
½ cup brown sugar
⅓ cup flour
1 cup chopped nuts
3 Tablespoons butter, softened
 
Crumble together with fork or hands. Sprinkle evenly over top of potato mixture. Bake at 350˚ for 35 minutes or until center is set.
