Heat butter in a skillet, add sugar and stir until melted. Stir in pineapple juice and ginger. Boil until slightly syrupy. Add pears, cook until tender for 5 to 10 minutes.

To serve — sprinkle with confectioner's sugar, add pear sauce and top with macadamia nuts.

Cream together margarine and sugar until fluffy, and add eggs. Beat well. Add sour cream. Sift together dry ingredients and add, along with rind, juice and extract. Beat all together until well blended. (Batter will be very thick). Spoon into well-greased tube pan and bake at 350 degrees for about an hour. Remove from oven, cool 10 minutes, and turn out on plate. While cake is still warm, pour over it a mixture of 1 cup sifted confectioners sugar blended with juice of one orange.
