This is a very simple recipe for making Cumin Rice. Traditionally there are two methods of making Cumin Rice. The first method the spices are sauteed first in oil and the rice is cooked along with the spices. this technique is mostly used in restaurants (This recipe). The second method is where the whole spices are fried first and the rice is cooked along with the spices. this method is similar to that making of pulao.
If you want a fully spiced rice flavour than the second method would be the better option. The flavor of jeera/cumin and the whole garam masala combines really well. You can add black peppercorns/kalimirch, mace/javitri and additional spices to it. In this method you can also add some onions while making the rice. It is worth mentioning that the cooking time takes longer.
The reddish orange and yellow color is saffron or turmeric. If you want to add some color, then add either of them.
Serve jeera rice hot or warm with a dal or vegetable/paneer curry
