Day One: Separate the eggs with the whites into a large mixing bowl for a countertop mixer and the yolks in a small mixing bowl. Beat the egg whites until stiff. beat the yolks until foamy then add to the whites. Gradually add the sugar and continue beating until the mixture is creamy and the sugar is dissolved. Now add the fruits, nuts, and lemon zest to the egg mixture. In another bowl, sift together the flour, spices, and baking powder. Slowly add the dry ingredients to the egg mixture. The dough will get very stiff so if you do not have a powerful mixer, you will need to mix by hand at some point. Once all ingredients are incorporated and mixed well, cover this dough and put in the refrigerator overnight to season.
Day Two: Preheat the oven to 375 degrees Juice the two lemons and set aside. Prepare the cookie sheets with Pam spray or use parchment paper for each batch. Sift flour onto your rolling pin and surface. Scoop out a large handful of dough from the bowl, cover it in flour and roll to about 1/4" thick. Cut with a round biscuit cutter (about 1 1/2" diameter or smaller) and place on the prepared cookie sheet. These do not spread as they cook so spacing isn't necessary. Make sure you work with the dough scoop you started with until it is all used up. Do not add fresh dough to the scoop as this does not work well for this cookie. Once the sheet is full, take the lemon juice in a spoon and gently, carefully rub the back of the spoon over the top of each cookie coating them with juice. Be careful not to spill excess juice onto the sheet around the cookie as this will burn. Now bake the cookies for about 13-14 minutes or until lightly brown. Remove from the oven and take from the cookie sheet onto a clean dishtowel spread out onto the counter to cool. This recipe makes about 25 dozen.
The most difficult part of this recipe is resisting temptation, but it is the secret to making them a special treat. Put the cookies away for at least two weeks to "season" totally before you enjoy. You will know when it is time!
