Break up the almond paste into about 2" chunks. Put all the ingredients into a large mixing bowl. You can use a hand mixer or your hands to get it all combined. It'll be sticky but workable.
7 ounces (198 grams) almond paste, 1 cup (100 grams) finely ground blanched almond flour, 1 1/2 teaspoons vanilla extract, 1/2 teaspoon almond extract, 1 cup (100 grams) powdered sugar, 1 large egg white, 1/4 teaspoon salt
Place the sliced almonds into a small bowl (big enough to dip dough logs in).
Form about a 1.5" (24-gram / 20-gram for paleo) ball and roll into a little log.
Beat the egg white a little with a fork and brush egg white all over the cookie.
1 large egg white
Dip the cookie into the sliced almonds.
1 cup (100 grams) sliced almonds
Form into a crescent shape. Place them about 2" apart on the baking sheet. They'll puff up quite a bit.
Bake for 14-15 minutes or until lightly browned.
Let cookies cool on the baking sheet for about 5 minutes and then transfer cookies to a cooling rack to cool completely.
Once cooled, combine the melted chocolate + coconut oil in a small bowl.
2/3 cup (113 grams) semi-sweet chocolate, 1 teaspoon coconut oil
Dip the ends of each cookie in the chocolate. Place back on a parchment-lined sheet and let them harden completely. I put them in the fridge for 30 minutes and that does the job.
Once the chocolate has hardened, store in an airtight container for up to 2-3 weeks. They can also be frozen for several months.
