Line an 8x8 pan with parchment paper, making sure to leave about an inch of overhang on each side. Alternatively, line an 8x5 loaf pan with parchment paper, leaving an overhang.
Put the cashews into the food processor. Process the cashews for about 1 minute, until they become a coarse meal.
1 ½ cups (200 g) roasted unsalted cashews
Pulse in the salt until well distributed.
½ tsp kosher salt
Add the dates. Process for 3-5 minutes, until the dates are broken down and the mixture forms into a ball.
1 ½ cups (½ lb / 227 g) pitted Medjool dates
Put the mixture into the prepared pan. Using clean, damp hands or the bottom of a measuring cup, press the mixture firmly into an even layer.
Chill in the fridge for at least 30 minutes.
Use the parchment overhang to lift the chilled recipe out of the pan. Cut into 8 even bars. Store in an airtight container in the fridge for up to 2 weeks with strips of parchment paper between each bar.
