Once you have the paste, making the sauce is easy! All you need is:
- some water
- a tad of salt.
Take some tahini paste, put it in a little bowl that you can mix it with stuff. Make as much or as little as you want, keeping in mind that the tahini sauce keeps in the refrigerator for about a week. Gradually add some water, you will need about 50% as much water as paste. You may need some more, you may need some less. So I recommend adding the water gradually. When you add the water, you'll notice that the tahini paste changes color! It actually becomes whiter! Neat, huh? You'll want to get it to have a consistency similar to cake batter. That is, somewhat runny but not too watery.
