I prefer to buy hulled, raw sesame seeds, and toast them as needed. If you prefer bite-sized truffles, use a smaller scoop, and you should get about 20. If you’re doubling the recipe, then a food processor might work fine. Otherwise, I find my mini chopper does a better job. And be patient, just when it looks like this won’t work, it all comes together. Promise. I sweat bullets every time, and yet it always works out!
