Hi - does the recipe use Tahini sauce, paste, creamed or crushed please?

I'm not familiar with some of the variations you mention, but this recipe uses tahini, the creamy puréed kind. At Zahav, they like to use Soom Foods' tahini, which is available on Amazon, but you can use any brand you like: http://www.amazon.com/Soom-tahini-12-oz-sampler/dp/B00JKPRQOE/?tag=food52-20
