A sesame seed paste used as an ingredient in many Mediterranean recipes including tabouli, hummus and more.
Tahini is a paste made from crushed/pureed sesame seeds. It is often food in a jar (or can) and is mixed with olive oil to change the consistency, per preference.
NOTE: Tahini has no meat or dairy products in it and is basically like Olive Oil. You can keep it indefinitely (re-sealed after being opened). It does not need to be in a refrigerator but should be placed in a cool, dry food storage area. It should last until it is consumed once it is opened, if re-sealed properly with the jar lid.
