This dish got an enthusiastic thumbs up from my dinner guests tonight, and a 5 star rating. The men especially enjoyed it, and I am glad that I doubled the recipe to have some left-overs for tomorrow. When I make this next, I think I will follow a method I use in East Indian cooking, namely, I will fry the cumin seeds briefly in about 1 tsp of oil till they turn reddish, and then add and fry the onions, ginger and garlic till softened before making the rest of the sauce as written. I certainly enjoyed the sauce very much, but I wonder if cooking the garlic and ginger longer would further enhance the flavour. This is a dish that will be appreciated for family meals, but is certainly attractive and tasty enough for company.
