Preheat oven to 250 degrees.
Roast cashews on cookie sheet for 30 minutes, stirring after 15 minutes.
Let cool for 5 minutes and then put in a food processor.
Process until cashews are smooth, scraping down sides occasionally.
Be patient, this process can take at least 8 minutes, but watch for all of a sudden it will be smooth.
Once smooth, add salt, vanilla and honey.
Process for a few minutes.
Depending on your cashews and food processor if you find it is not getting smooth you can add ½ Tbsp of canola or grapeseed oil.
I store my nut butter in the fridge, but I really think homemade cashew butter added a real richness to the curry.
Plus you can use the cashew butter for so many things.
