Method
● Spoon the tahini paste into a bowl, add the water gradually and beat constantly with a whisk. At first the tahini will become denser (don't panic!) and then it will start to loosen up. Stop when you hit the texture you like.
● Add the lemon juice and salt to taste. You can keep the sauce refrigerated, tightly covered with clingfilm, for up to 2 days (it goes a bit thicker in the fridge).
