1/2 cup currants
1/3 cup margarine or butter
1 3/4 cups all-purpose flour
3 tablespoons sugar
2 1/2 teaspoons baking powder
1/4 teaspoon salt
1 tablespoon grated orange peel
1 egg -- beaten
4 tablespoons half-and-half (4 to 6 tablespoons)

Heat oven to 400º. Soak currants in warm water for 10 minutes to soften; drain. Cut margarine into flour, sugar, baking powder and salt with pastry blender until mixture resembles fine crumbs. Stir in orange peel, egg, currants and just enough half-and-half until dough leaves side of bowl.
Turn dough onto lightly floured surface. Knead lightly 10 times. Divide dough into 2 parts. Roll or pat into two 6-inch circles about 1/2 inch thick. Place on ungreased cookie sheet; brush with beaten egg white.
Bake 10 to 12 minutes or until golden brown. Immediately remove from cookie sheet. Cut into wedges to serve.
