Tahini (Sesame Paste — Cold Press vs Roasted — Ratios)
Sesame cultivation and oil production dates to at least 3000 BCE in South Asia and the Middle East. Tahini as a paste is documented in the medieval Arab cookbook Kitab al-Tabikh and was historically an ingredient in hummus, halva, and multiple regional preparations across the Levant.
Tahini — hulled sesame seeds ground to a smooth, pourable paste — is the most versatile ingredient in Middle Eastern cooking, functioning simultaneously as a sauce, a dip, a salad dressing, a baking fat, and a flavour base. Good tahini is not merely sesame paste: it is the result of sesame seeds properly sorted, hulled, sometimes lightly toasted, and stone-ground until the natural oils release and the paste flows freely. Bad tahini is bitter, gritty, and intolerably thick.
The cold press vs. roasted distinction matters enormously. Cold-pressed tahini uses raw or very lightly toasted sesame seeds, producing a lighter, more delicate flavour — nutty without bitterness, with a natural sweetness. Deeply roasted tahini has a more intense, slightly bitter flavour that suits robust preparations. Israeli and Lebanese traditions favour the lighter version; some Chinese preparations (sesame paste — zhī má jiàng) prefer the roasted style. Top-quality brands separate into layers of solids and oil — this is a sign of quality, not spoilage; stir before use.
The ratios for tahini dressing (the sauce served throughout the Middle East alongside falafel, shawarma, roasted vegetables, and grilled meats) are: equal parts tahini and cold water, plus lemon juice, garlic, and salt. When water is added to tahini, it initially seizes — this is correct and alarming to those who haven't seen it before. Continue stirring and adding water in small increments and the paste loosens into a smooth, pourable cream. The lemon juice further lightens and brightens it.
Beyond savoury applications, tahini is fundamental in pastry: halva is tahini mixed with cooked sugar; tahini cookies, tahini chocolate cake, and tahini-swirled brownies are contemporary developments of extraordinary merit. A good tahini introduces nutty richness to baking without the sweetness of nut butters.
