I have used gingelly oil for this rice to give nice aroma.
You can fine chop tomatoes so that it nicely blends with rice,even you can grind and add if you wish.
I have used normal rice but you can make it with any aromatic rice like basmati or zeeraga samba.
I have added little gingelly oil to cooked rice to get the grains of rice separated and puff up the rice.
