Tahini Sauce Seized
Tahini that clumps and seizes when liquid is added is a common problem with a simple fix — here's how to turn seized tahini into a silky, creamy sauce.

Ingredients on hand
- tahini (sesame paste)
- lemon juice
- garlic
- cold water
- salt
- cumin (optional)
Why it happened
Tahini seizes because sesame paste is a dense emulsion of ground sesame solids and oil. When water is added, the water molecules interact with the starch in the sesame solids and tighten the protein network before the oil can re-emulsify around the water — creating a thick, paste-like clump. This is the same phenomenon as seizing chocolate. Continued addition of water past the seizing point exceeds the network's capacity and the emulsion suddenly re-forms with water as the continuous phase.
The fix
- 1Add cold water, 1 tablespoon at a time, whisking vigorously between additions — the sauce will thicken and seize at first, then suddenly loosen into a creamy emulsion
- 2Keep whisking past the seizing point — it takes about 3–4 tablespoons of water and then a sharp vigorousness to break through
- 3Add the lemon juice last, after the water is incorporated — adding acid first often causes more aggressive seizing
- 4The final sauce should be thick and pourable, like heavy cream
If it's still wrong
- Add more tahini to the seized mixture and stir — the additional oil from the new tahini can help break the seized state by providing more fat to emulsify.
- Warm the seized tahini gently in a double boiler for 30 seconds while stirring — heat loosens the protein network and makes the emulsion easier to break.
Prevent next time
- Add water in very small amounts (1 tablespoon) and whisk thoroughly between each addition — never pour water directly into tahini.
- Use cold water, not warm — cold water slows the initial starch interaction and gives the oil more time to emulsify.
Substitutions
- tahini→sun butter (sunflower seed butter) for a nut-free version that behaves identically
- cold water→aquafaba (chickpea liquid) for a slightly thicker, creamier sauce
