Step #15 Madhur Jaffrey's Flavours of India - Punjab This rich flavoursome dish originates in the fertile Punjab, a state now divided between India & Pakistan.
Step #16 There is nothing more important to a Punjabi man's diet than bread, & meals are accompanied by flat round cornbread rotis or rich, flaky pan-fried paratha layered with ghee (clarified butter).
Step #17 Rice is reserved for special occasions or for rice pudding, for the only food that makes a Punjabi feel he has eaten a proper meal is his bread! You of course, can serve this dish with plain boiled rice.
