Soak the cashews in water for a couple of hours (not longer than 8 hours) to make them softer and neutralize the phytin acid. This is especially important if you consume high amounts of nuts daily.
After the soaking pour away the water and add your cashews into the food processor and then let it slowly start chopping.
Give your food processor a break from time to time when it gets too hot.
Be patient and persistent. It can easily take you 20-30 minutes if you want your result to be extra creamy.
Anmerkungen / Notes
You should store the cashew butter in the fridge and use it up within a week. If you're not sure if it's still good just take a smell at it or taste it.
