Making Tehina on Shabbat

Is one allowed to make tehina on Shabbat (from the paste, its a thick paste, you add water/lemon/spices and it becomes more liquidy when you mix it)? If not, does it become assur to eat if someone violated the issur?

You can add water and lemon but not spices since its attaching the spices together. But you can do it buy mixing beshinui.
