Makes 1 loaf
Sift dry ingredients into a bowl.
Chop the dried fruits and candied peels and add, with the grated lemon rind, to the dry ingredients. Mix well.
Cream the butter and sugar until smooth. Add the 1 egg and beat. Add the egg yolk and beat until light and smooth. Add the beer and beat again. Pour in the fruit mixture, blending well.
Spoon into a well-greased and floured baking pan (9 × 5 × 3, or a little larger). Level the dough in the pan with the back of a spoon.
Bake in a preheated 350° oven 1 hour, or until browned on top. Remove from oven and let the loaf stay in the pan 5 minutes. Turn out on a rack. Spread top with a thin glaze, letting some drip over the sides.
