Optional: Toast sesame seeds in a grilling pan over medium-low heat, stirring constantly until the seeds are golden and fragrant. Alternatively bake in the oven at 360F/180C, until golden, about 5 mins.

Add sesame seeds into a food processor then process for a min, or until crumbly.

Add a little salt and oil, and pulse for a couple more mins, scraping the bottom and sides of the food processor a couple times.

Keep pulsing all the ingredients until you reach a smooth, creamy consistency. Add a little more oil if necessary.
