* Tahini is an everyday product at Middle Eastern markets and is becoming more and more common at larger grocery stores but you can also purchase it online (this is a super buy, 2 large jars for 10.49 - and free shipping if you have Amazon Prime). Once you've opened tahini, store it in the refrigerator to keep it from getting rancid.
** Neufchâtel cheese will usually be found right next to the cream cheese in the dairy section of the grocery store. It's lower in fat and has a slightly higher moisture content. If you can't find it or don't want to run out and buy it, cream cheese will work just fine.
