You can buy a special Persian rice maker. We have one but I don't like using it because I think it makes the tadik really hard and chewy and not crisp and crunchy as it should be. I much prefer to make it myself. But it's useful if you are busy and have other things to do.
To begin with buy the best rice that you can. We use Basmati. Usually Tilda which I would really recommend. It grows up in the mountains of the Himalayas and has a lovely aromatic flavour....I could eat a bowl of it with nothing but a bit of natural yoghurt and a sprinkle of sumac. That's a spice made from ground berries that have a slightly tart lemony flavour, and are used a great deal in Persian cooking.
The rice is cooked in two stages. This is stage one:
Measure the rice into a saucepan, one cup per person. Then wash it until the water runs clear. This may take a little while, five or six washings or even more, but is a really important stage as it not only removes any dust, but I'm told that it also reduces some of the starch which makes the rice sticky. I've done a bit of research and it seems the debate is out on this one...But washing it this way does keep the blades separate and stops it being sticky, which is what's required for this method.

Then cover with plenty of cold water and season with sea salt. Then bring the rice and water to the boil, reduce the heat and cook until the rice is al-dente. Remove from the heat and drain into a colander.
Stage two:
Add a little water and oil into the empty pan and place on the hob on a high heat to heat up the water. Then return the rice to the pan. Cover the lid with a tea-towel and place securely on the pan. Once you can hear the pan sizzling, turn down the heat and leave for thirty to forty minutes. If you splash cold water onto the side the pan it should again make a sizzling sound indicating that the rice is cooked.
Place the pan in cold water to cool down. Just for a few seconds as you don't want the rice to actually get cold. Sometimes it rattles and shakes when it hits the cold water. I always think good this is going to have a good crunchy layer when it does that. It should then be easy to release the rice. Empty the contents including the lovely crunchy tadik......double yum....
nb. Although by preference I usually use a heavy cast iron pan/cooking pot for cooking, when I'm making Persian rice I always use a thinner stainless steel pan. It just works much better. I find that it's easier to remove the tadik from the pan and also easier to check with 'the sizzle' when the rice is ready.
