Step 1

Set up your grill for indirect heat. If using a charcoal grill, build the coals on one side only. If using a gas grill, heat one side only.

Step 2

Prick the eggplants all over the surface with a fork. Place on the direct heat side of the grill or directly on to the coals, close the lid of the grill and char on all sides, turning once the skin begins to darken and crack, about 5 minutes per side. When the eggplants have softened through, remove to a resealable bag and allow to steam for a few minutes. When cool enough to handle, peel the eggplants and discard the skin and most of the seeds.

Step 3

In the meantime, make the tehina. Break up the garlic cloves into a blender or food processor, leaving them in their papery skins. Add the lemon juice and salt and blend into a pulpy purée. Press the mixture though a strainer set over a bowl containing the tahini. Whisk to combine; the mixture will thicken and seize up. Whisk in the ice water, smoothing out into a loose sauce.

Step 4

Add the cleaned eggplant to a blender or food processor while still warm. Pour in all the tehina and blend until smooth. Taste and adjust the seasoning, adding more salt and lemon juice if needed. Serve with olive oil drizzled over the top.
