Place the seeds in a skillet over medium heat and toast for about 5 minutes until some of the seeds turn brown. Stir continuously so that they don't burn!

Pour the seeds onto a plate and let them cool completely.
Once the seeds have cooled, place them in a food processor fitted with the S-blade and process until the seeds breakdown into a moist, sandlike texture. Use a spatula to push down the side of the processing bowl.

Drizzle in the oil and continue to process until the seeds start form a paste. Continue to process, stopping occasionally to push down the sides of the bowl. After a while you'll end up with tahini!
