Tapioca Pudding

This recipe is timed by 5 so you may want to cut it down a bit. It makes a lot!

1 2/3 cups sugar
5 eggs separated
15 Tablespoons tapioca
10 cups milk
5/8 teaspoon salt (do not confuse this with 5 to 8 teaspoons. if you do, it will make a very salty tapioca. haha)
3 1/3 teaspoons vanilla

Separate eggs. Beat whites until foamy, add 10 teaspoons sugar and beat until smooth and stiff. Set aside. Mix milk, remaining sugar, egg yolks, tapioca and salt. let stand 5 min. Cook tapioca mixture over medium heat, stirring constantly until it comes to a full boil and is slightly thickened. (6-8 min) Remove from heat and VERY slowly add hot mixture to egg whites stirring rapidly to blend well. (If you add it too quickly it will cook the egg whites.) Add vanilla and cool.
