Rogan josh is one of the national dishes of the Kashmir region of India, though it was introduced by the Moghuls - who were in turn strongly influenced by Persian traditions and culture. The deep red colour of the dish comes from the use of lots of Kashmiri chilli, which make it rich and flavoursome - with not too much heat - and add a fantastic depth of flavour. It’s served here with some side dishes typical of the region - a simple saag bhaji, pilau rice, masala rotis and cucumber raita. Finally, after the rich curry, there’s a fruity mango kulfi flavoured with saffron, cardamon and rose to cool everything off.
