Syrian Cooking's ingredient list (garlic, canned or fresh beets, tahini, olive oil) is straight-forward as are the directions. I would add only that if you used canned beets, especially beet strings, the boiling process is not necessary.
What is imperative is ample olive oil for creaminess and quality tahini, which provides wonderful nutty notes that balance the sweet botanical flavor of the beets and the tangy garlic.
I am not ashamed to say I ate much of my product with a spoon; however, pita toasts are probably more dignified.
