recipe for lebanese style garlic sauce?

NN - See the link below, it is the homepage of the lady who makes the sauce in the youtube clip that you cannot see. EXCELLENT RECIPE - It is exactly like the restaurant lebanese garlic sauce. The first time I made it, turned out perfect, the 2nd time it WOULDN’T thicken at all so I slowly poured in some cornflour boiled in water gloopy solution to rescue it whilst still running the processor. BTW - I used Sunflower oil instead of Canola oil.
