In a food processor, add peanuts and salt and turn on to process.
As peanuts start to break down and clump, stop the food processor and scrape down sides.
Continue to process the peanuts and slowly add oil while machine is running. Stop to scrape sides as necessary and process until peanut butter is smooth and creamy.
