Grind the almonds to a powder. A finer powder is best, but it doesn't need to be like flour. Put the almond powder in a large mixing bowl. Next, blend the dates in a blender or food processor until they are in very small pieces and partly pureed. You may need to cut them in half before you put them in the blender, depending on how powerful your blender or processor is. Put the date pieces/puree in the bowl with the almond powder. Knead the mixture for 5 minutes or so. Heres the trick: At first, it will seem as if it will never blend. But after a few minutes, the heat generated from kneading will bring out the oils. If after 5 minutes this just isn't happening, wet your hands--don't add water! Continue kneading. Kneading is the key to success in this recipe. Eventually your mixture will stick together quite nicely. Form a brick or bar. This is tremendously tasty and full of protein.
