Yams with Nutmeg Struesel

I love yams, and I've tried them prepared a lot of ways, but this is by far the most delicious.  It's always a hit. Sorry, there's no picture because it was consumed too quickly.

Ingredients:

3 pounds yams, untrimmed

1 1/4 cups flour

1/2 cup brown sugar

1/2 tsp kosher salt

1 stick butter, melted

1/3 cup sugar

Juice of one lemon

1 tsp kosher salt

1 tsp grated lemon zest

3 Tbsp. water

Directions:

1. Boil yams whole in salted water until tender when pierced, about 40 minutes. Drain and let cool. 

2. Mix together flour, sugar, salt and melted butter to make large crumbs. 

3. Peel and slice cooled, cooked yams in 1/2 inch slices. Layer in a buttered baking dish. 

4. Bring to a boil the remaining ingredients and pour over the yam slices.  Sprinkle with the streusel crumbs and bake at 400 degrees F for 30 minutes, until browned and bubbly.
