Recipe from Alton Brown
15 ounces peanuts
1 teaspoon salt
1 1/2 teaspoons honey
1 1/2 tablespoons peanut oil
Place the peanuts, salt, and honey into the bowl of a food processor. Process for 1 minute. Scrape down the sides of the bowl. Place the lid back on and continue to process while slowly drizzling in the oil and process until the mixture is smooth, 1 1/2 to 2 minutes. Place the peanut butter in an airtight container and store in the refrigerator for up to 2 months.
