It was only the first time cooking rice in the PC. My method was like: add ghee, add whole spices (cassia, star, bay, fennel, cardamoms, cloves) cook between 60s and 90s in medium heat, throw in 3 cups of unsoaked rice (this time I didn't bother to pre-soak it), mix the grains in the ghee/spices, add plenty of hot water from the kettle (until it covers 1" above the rice) add salt, add g&g, cover, high heat. As soon as the pressure cooker starts whistling bring the flame to medium, wait around a minute, turn off and ensure all the pressure is released. Open. Fluff up. Add color. Put in a tray, cover with foil with a few pierces. (Cook the curry) pick some rice off and refluff the rice. Finito.
As for the the green cardamoms, they were obtained around january/february this year, were always kept in an air sealed container since then, although not always in a dark spot (odd night I forgot to move it into the pantry after cooking) and yes, I do crack the shell of the cardamoms to allow the seeds to do its work during the cooking. Occasionally while cracking their shell I get the odd seed/s that pop out and land on the counter near the shell and I always make sure to add these to the rice as well.
As far as I can tell, the green cardamoms still have that old green look, it's not brown in any way as far as I can describe them. The seads are dark brown or black!
