This lamb curry is so intensely flavourful. A rich, decadent sauce clings to the fork-tender lamb pieces – it’s hard to fathom the sheer fragrance and flavour in Kosha Mangsho, but in truth, it’s actually one of the easiest curries to make at home. Learn what’s behind the flavour…
Kosha Mangsho is traditionally a mutton curry, served the length and breadth of the Indian sub-continent. In this Bengali version, which can be made with mutton, goat or lamb we see ingredients typical of the region. This recipe for Kosha Mangsho features lamb - I like to cook my lamb off the bone for a less 'involved' eating experience when cooked, but I'll often cook this with goat or using thick cut lamb loin chops with the bone in. You can decide which you prefer. I don't think the flavour is affected either way.
Talking of flavour, kosha mangsho is not short on it! The curry has one of the most intensely satisfying and complex flavours. Let's break it down to show you how to create all that flavour yourself.
What is Panch Phoron?
Eastern India and the surrounding areas are synonymous for their specific spice blends - Panch Phoron is one such mix. A whole-spice mix that's added to many dishes to help give their unique flavours. Panch Phoron features 5 key spices:
- Fenugreek seeds
- Mustard seeds
- Fennel Seeds
- Nigella Seeds
- Cumin Seeds
The spices are simply blended together whole. You can buy panch phoron pre-mixed, but it's not so taxing to mix your own - see the recipe below for quantities. You can keep it in a jar for months too, ready for any eventuality.
Marination of a nation!
Any great meat curry benefits from a lengthy marination. In all honesty, I've made this curry without any marination at all and the taste is still amazing, but I must admit, the meat after marination is definitely improved. Do whatever makes you happy. The marinade for kosher mangsho is also the sauce - so to keep things easy, I add yoghurt and pretty much everything else to reduce the number of cooking steps.
To get our curry started we need to fry the panch phoron and some more whole spices briefly to help activate the oils and draw out the flavour. In Bengali cuisine, mustard oil is very common - it has a wonderful flavour and adds another layer of complexity to the dish. In this recipe, I've combined Ghee (clarified butter) with mustard oil which gives a wonderful flavour. Once our spices have fried briefly, they start to hop around the pan - in go the onions and we fry until soft.
Then it's as simple as adding the marinated meat and some water. The lid goes on and we cook for about 1 1/2 hours until the lamb is fork-tender. If the meat is on the bone, it might well need a little longer but 1 1/2 hours should be enough time.
As this is a dry curry, after the inital cook, I remove the lid and turn up the heat - I let the sauce reduce vigorously for 10 minutes, stirring every minute or so to avoid the meat sticking. I reduce the sauce considerably so that it clings to the soft meat.
I like to serve my kosher mangsho with Indian bread as it's perfect for scooping without any mess. That said, basmati rice is no second fiddle! Once you taste this amazing curry, I'm sure you'll agree that it's an absolute winner on every level. Perfect texture, perfect colour and perfect flavour - the trifector!
