It does look like the biryani has the curry (vegetable or curry sauce) already mixed into the rice.
Anyone got idea what silver looking ingredient goes in at 20 sec.
Bit frustrating video starts part way. Looks like chicken, green chilli, garden peas, spice and water already added. Possibly even the mushroom.
Have now seen 3 methods of cooking biryani - dipuraja and h4ppy-chris being the others.
Have not tried the Glasgow or h4ppy-chris methods which are along the same lines except rice into curry c/w curry into rice.
I still feel I favour dipuraja. Has anyone compared the methods.
