Heat a heavy, wide-bottomed sauté pan over medium-high heat.
Add the sesame seeds and toast lightly - about 2 minutes, shaking the pan so they toast evenly. Two tips here: a) I am a messy cook with limited arm strength. I have a great fear that if I toss a pan, food will end up everywhere, therefore, I tend to just vigorously stir rather than toss. b) Keep a careful eye on the sesame seeds as they go from toasted to burnt really quickly. As soon as they start to brown, they are done.
Transfer to a bowl and let cool completely.
Next, you'll process the toasted seeds with the olive oil.
Put the toasted sesame seeds in a food processor and drizzle in the olive oil. As you can see, I poured rather than drizzled. It worked just fine!
Pulse for 3-5 minutes, or until it's as smooth as you can get it.
Add a little more olive oil if necessary.
Remove from food processor and store in the refrigerator.
