Whip eggs until thick and creamy. Add sugar a little at a time and whip until light and fluffy or lemon colored.
In small bowl whisk flour with baking powder and a pinch of salt. Add to egg and sugar mixture. Blend until flour disappears.

In small sauce pan, heat milk and butter just until butter melts. Slowly pour hot milk/butter mixture into batter and stir (not whip) until well blended, scraping down sides and bottom of bowl. Add flavoring of choice; I used 1/2 teaspoon vanilla and 1/2 teaspoon lemon flavoring.

Pour into well greased and floured loaf pan. Bake at 350° for 25 to 30 minutes. Mine took 30.
