When the nuts are cool, set aside 1/4 cup toasted walnuts to pulse in at the end. Add the rest of the nuts to your food processor or high-powered blender (I used my Vitamix
). Process for about 3-6 minutes, scraping down as necessary. Your time might be shorter if you’re using a high-powered blender - it will take a little bit longer in the food processor and require more scraping down.
