In the bowl of your stand mixer place beat your 6 oz almond paste and 7 1/2 oz granulated sugar together. Add 2 oz of your 2-3 oz egg whites.
Add 15 oz butter in all at once and mix together until well blended.
Sift 6 oz all-purpose flour and 12 oz cake flour. Then add to your butter mixture along with the 1/2 tsp salt
Add extracts
Try to pipe a little bit of your cookie dough. It can be quite thick and difficult to pipe. If it is too thick add the remaining 1 oz of egg whites at this time.
Fill your piping bag with 1/2-1 cup of cookie dough at a time so you can easily squeeze it out. Pipe your cookies into whatever shapes you desire onto a lined cookies sheet.
Bake cookies for 8-10 minutes until they are barely browning around the edges.
Allow cookies to cool and then you can decorate.
