Tahini Tarator
Tahini Tarator is a magical cold emulsion. Pure sesame paste (tahini) is naturally thick and bitter. Whisking it with lemon juice causes it to temporarily seize into a dry paste, but slowly adding cold water relaxes the proteins and creates a smooth, creamy, ivory-colored dressing.
History & Origins
Sesame paste has been cultivated in the Middle East for millennia. The combination of garlic, lemon, and tahini represents the core flavor triad of Levantine home and street cooking.
The Science
When lemon juice is added to tahini, the acid coagulates the sesame proteins, causing them to group and seize. Adding cold water hydrates these proteins, letting them separate and trap oil droplets in a creamy emulsion.
Technique
Do not panic when the tahini turns dry and chalky after adding the lemon juice. Keep whisking and add water in a thin stream; it will smooth out beautifully.
Common Mistakes
Using warm water. Warm water will not cool the emulsion, causing the sesame fats to separate and turn the sauce oily rather than creamy.
Chef's Notes
Use a smooth, light-colored tahini (usually imported from Lebanon or Palestine) to avoid bitter, dark hulls.
