This is a North Indian take on our stuffed பாகற்க்காய் (bitter gourd). A bit labour intensive but, well worth the effort. In this method I bake the stuffed karela instead of deep frying, so the weight watchers can also indulge.
A word about the dry spice mix used. It is called panch phoron or five spices. This is traditionally used in West Bengal and other North Eastern states for their fish dishes but has been adopted by the North Indians for some of their dishes also. This is just a dry mix of equal amounts of mustard seeds, cumin seeds, fenugreek, fennel seeds and kalonji or nigella seeds. This is always used whole and not ground. I always keep this premixed and readily available as this adds a lovely flavour to North Indian dishes.
