2 egg whitesInstructions
In a saucepan, mix egg yolks with a small amount of milk. Add tapioca, salt, and remaining milk. Bring mixture to a rolling boil, stirring constantly. Remove from heat. (The mixture will be thin; don’t overcook.)
Melt butter in a small saucepan; add sugar and stir until completely melted and mixture boils. Add to tapioca mixture and mix well. Add flavoring. In a large bowl, beat egg whites (at room temperature) until just stiff enough to hold shape. Fold hot tapioca mixture gradually into beaten egg whites. Chill well; mixture will thicken as it cools.
