In a food processor fitted with the steel blade, grind the cashews to form a coarse flour, about 25 seconds.
Add the tahini, cinnamon, cardamom, nutmeg, and salt.
Process to combine.
Add the maple syrup and process just until the mixture forms a ball.
Roll the dough into 1-inch balls. (Don’t worry if the dough is oily. That will disappear as the balls chill.)
Refrigerate for at least 1 hour before serving.
Store in an airtight container in the refrigerator.
Notes
Technique Tip: To toast the cashews, place them in a dry skillet set over medium heat. Toast, shaking the pan occasionally, until fragrant and lightly golden, 4-5 minutes.
