Step #1 Using an electric mixer, 1 egg & an egg yolk, beat the butter until light & fluffy and slowly add the sugar, & 3 tbsps of the Cognac, beating thoroughly after each addition.
Step #2 Sift 2 c of the flour with the salt & baking powder & add slowly to the batter, while beating on medium speed.
Step #3 Remove the beaters & finish by hand, adding only enough flour to make a soft dough.
Step #4 Knead.
Step #5 Cover & put in the fridge for at least 30 mins.
Step #6 Meanwhile, slice the apricots into uniform pieces & place this in an enameled pan.
Step #7 Soak the figs & raisins in the remaining Cognac until swollen, then mince & add to the apricots along with the orange rind, jam, then cook over med-heat/flame until thick, & lemon juice & stir in theto the apricot mixture, stirring constantly with a wooden spoon.
Step #8 Cool.
Step #9 Remove the dough from the refrigerator & set aside about one-third for the latticed top.
Step #10 Using your fingers (the dough will be too soft to roll), press the larger portion of dough into a buttered 9 x 12 x 2-inch baking pan, pressing evenly about 1/4-inch up the sides.
Step #11 Pour the filling into the dough-lined pan.
Step #12 Divide the remaining dough into walnut-sized balls & roll each ball into 1/2-inch strips.
Step #13 Using the strips, make a lattice over the top of the pastry.
Step #14 If using a glaze, beat the remaining egg white slightly with a fork & brush on the dough stips.
Step #15 Bake in a moderate oven (350 F) for 45 mins, or until golden in color.
Step #16 Remove & cool in the pan on a rack.
Step #17 To serve, cut into 1-1/2-inch (or smaller) squares with a sharp knife.
Step #18 Note: You may prefer to use peaches & peach jam, strawberries and strawberry jam, & so on, instead of apricots; also sliced candied peel adds a colorful note when substituting for figs; & slivered almonds may be added to the filling.
