• Preheat the oven to 350ºF/180º and line two baking sheets with non stick parchment paper.
• Break up almond paste with fingers into small pieces. Pulse in the food processor until sandy texture. Add sugar and continue to pulse until well combined. With processor running add egg whites slowly through the chute until the mixture forms a thick dough. It shouldn't be runny so you may not use all the egg white.
• Place the pine nuts into a flat bowl.
• Use a teaspoon to scoop up the mixture and with another teaspoon scrape it into the pine nuts and toss well to coat. Press in the pine nuts and shape to form a dough ball.
• Place balls onto baking sheet leaving a bit of room for spreading.
• Bake for 8-10 minutes, rotating trays to ensure even browning until just beginning to become golden. Time take to bake will vary depending on the almond paste used. The cookies may take longer even up to 20 or 25 minutes.
• Remove from oven and allow to cool for a couple of minutes until the cookies are firm. Then transfer to a wire rack to cool completely.
• Store in airtight container at room temperature for 4-5 days. If you’re keeping these for any longer, it would be best to freeze them.

Homemade Almond Paste (if using homemade)

• Combine the almond flour, powdered sugar and salt In the food processor.
• With the motor running drizzle in the egg white and almond extract.
• Process for 2 or 3 minutes until the mixture starts to come together. If it doesn’t look like it is coming together. Stop the motor, lift the lid and press some of the mixture together. If it sticks together like stiff dough then it’s perfect.
• If it doesn't stick together, with the food processor motor running, drizzle in extra egg white a little bit at a time until the mixture sticks together.
• Scrape the mixture onto a work surface and knead it into a dough for a minute or two. A lot of oil will come from it. That’s perfectly normal.
• Form into a thick log or flat disc and wrap well in plastic.
• Refrigerate for at least a day for the flavors to develop
