If you don't have a nutcracker on hand, there are still plenty of ways to crack open an almond. The most popular method is to use a hammer. Place the almond on a cutting board or other hard surface, and then carefully hit it with the flat side of the hammer until the shell cracks open.
Another option is to place the almond inside a Ziploc bag, and then use a rolling pin or other heavy object to crush it. You can also put the almond in between two hard surfaces (such as two plates) and then twist them back and forth until the shell cracks open.
Once you've crackedopen the shell, simply remove the edible part ofthe almond and enjoy!
