Preheat oven to 350°.
Place almonds in food processor and process for 25 seconds.
Add sugar, flour, cinnamon and butter. Process until it becomes a coarse meal.
Add egg and egg yolks and mix with a fork until it is moist. Dough will be quite sticky.
Divide dough into ⅔ and ⅓ balls. Refrigerate the ⅓ dough ball until well-chilled.
Press ⅔ dough into the a 8" greased springform pan pushing it part way up the sides.
Spread preserves or marmalade over the unbaked crust.
Remove remaining dough from refrigerator. Let it warm up for about 15 minutes. Roll into a round and if necessary add up to ½ cup flour to be able to roll it. Either cut into strips for a lattice effect or add the dough in a decorative way over the preserves.
Bake at 350° for 45 minutes or until the crust is golden brown.
