Portugal Cakes

Heat oven to 375°F butter muffin pans with 4 ounce cups.

Beat butter in large mixer bowl until creamy; gradually beat in sugar until well blended. Beat egg yolks with sherry in small bowl until combined; add to butter mixture. Beat until batter is light and fluffy, 3 to 4 minutes.

Beat egg whites in clean mixer bowl with clean beaters until stiff peaks form; fold whites into batter. Sift flour and nutmeg over batter; beat until smooth. Gently fold in currants.

Spoon batter into prepared muffin pans, filling each cup two-thirds full; bake until tops are golden brown, 20 to 25 minutes. Cool in pan on wire rack.
