You're very right that it is an old recipe, given to me by an aunt when I made the mistake of marrying at age 19, some 40 years ago. It calls for lemon extract, cake flour, 12 eggs, mace in some form of a portion of a tsp. and then finally whipping up a bunch of egg whites and folding them into the final mixture. Bake for an hour or so in a very slow oven in a tube pan. Darn....I've made this thing since the children were young but it's a once a year or less type thing with all the eggs (12) so I never made it even once a year! Any help you can find from old books would be great because one of the boys is coming w/his family for Thankgiving.
