Biriyani for Work

Decided to treat my team at work by making Biriyani - initially I was hoping to lookup a good recipe but didn't find anything that blew me away so ended up getting the Shan Masala prepackaged masala packet and followed it's recipe (on back of the package).  One addition to it was adding some roasted potatoes. 

A quandry I had was do I add lots of the chicken curry/masala to the rice and make a nice moist biriyani? this is not how I've seen it in restaurants it's usually nice dry separate grains with a layer of masala underneath.
I decided to stick to this notion and unfortunately it turned into a dry biriyani....  lesson learned fo next time.
