Preheat the oven to 350 °F (175 °C) and line a baking sheet with a piece of parchment paper.
Break up the almond paste into about 2" chunks and place in the bowl of a food processor fitted with an S-blade. Add the remaining dough ingredients and pulse until a dough forms. It'll be sticky but workable.
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.
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.
Dip the cookie into the 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.
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.
