Add the roasted almonds to your food processor, blend the almonds, stopping every few minutes to scrape down the sides. Depending on your food processor or blender, this can take anywhere from 3-10 minutes.
You will see your almonds transform from whole nuts to a mealy mixture and then to a butter! During this process, a sort of ball may form in your food processor. Keep going – this means you're on the right track!
After your almond butter has formed, give it a taste! I like to add a teaspoon of salt to mine. For sweet nut butters, you can add a tablespoon of agave or maple syrup or even sprinkle with spices like cocoa and cinnamon.
Transfer almond butter to a jar or airtight container and store in the refrigerator.
