For preparing the stuffed squid, first pulse the rice in the blender for a couple of times till you get broken rice. Wash well.
Add the rest of the ingredients and mix well with some salt.
Take one piece of squid, and through the open side, push in some of the rice mixture. Fill only half, not more than that. Seal the open side using a toothpick.
Repeat for all the squids till done. If you have any of the mixture remaining, add it onto the rice to be cooked.
Put all the ingredients mentioned "for rice" into a pressure cooker. Carefully place the stuffed squid and press into the between.
Cook on medium high for one whistle and then leave it on the lowest for 15 minutes. Switch off and allow the pressure to go by itself.
Open the cooker, slowly fluff up the rice. Serve hot.
