Add the peanuts and a pinch of salt to your food processor and puree until smooth, for about 5-10 minutes.
For Almond Butter
If your almonds are not toasted, lightly toast them in a large, flat pan over medium heat for 2-4 minutes, stirring frequently. Let cool.
Place your almonds with a pinch of salt in your food processor and puree until it becomes a creamy butter. Almond butter takes approximately 5-15 minutes, depending on the power of your food processor, and you may need to stop your food processor and push down the almonds in the first few minutes. Be patient - the almonds will go from whole nut to ground to a large, thick clump before smoothing out into a nut butter. If your food processor overheats and stops, give it a few minutes and try again, and then make your nut butter in smaller batches in the future.
Notes
Each recipe will make approximately 12 ounces of nut butter.
