Though it isn't usually considered to be strictly Omani food, my host family eats a lot of biryani. This morning, I helped cook lunch and so here is the recipe!
First, you need your ingredients. To start, onions...
Garlic, potatoes,cilantro, and tomatoes, all cleaned and chopped. Also a whole chicken, split into pieces.
Fry the onions in oil..
To make the masala, mix together the garlic, some turmeric, cumin, and chili pepper using a mortar and pestle.
Once it's mixed, add some green chilis and grind again.
And mix it in with the onions.
Add the tomatoes...
And potatoes and cilantro and black pepper and salt and some cardamom pods and cumin seeds and some more whole green chilis, as well as biryani masala mix (which you can buy or make).
Sit and let it simmer for a while, until the chicken is cooked.
While it's cooking, make the rice. Half-cook it. When it gets to that point, drain it. Then, put three-quarters of the rice in a pot, put the masala mix (what I just detailed) on top and finish off by covering it all with the remaining quarter of rice. Return it all to the stove and let the rice finish cooking. Then, stir it all and tada!
To make a nice sauce for it, put mint and yogurt in the blender. Optional is red chili powder.
