Haanser Dimer Kosha Jhal (Bengali Style Spicy Duck Egg Curry)

I love eggs, simply love, love them in any form, of course except raw. This time the ‘Dim Kosha’ was made with ‘Haansher Dim’ or Duck eggs. The first time I had Duck Eggs was when I visited my maternal ancestor’s place (mamar barir desh) in a laid back village which is few hours away from Kolkata. When I first time saw the eggs, they seemed pretty ordinary to me, just a bit larger. But when I tasted the curry it was out of this world and the yolks of those eggs were dark yellowish-orange in colour.

‘Dim Kosha’ or ‘Egg Kasha’ is a very popular egg dish in Bengali households. The ‘Kosha’ is a spicier version of the ‘Dalna’ where the gravy is thick and the hot quotient is high. The term ‘Kosha’ in Bengali means to cook the spices for a long time this brings out their flavor of the spices. In this case the dish is a duck egg curry with thick and spicy gravy. You can use either Chicken Eggs or Duck Eggs for this recipe. Since my father likes to have it with roti and he prefers to have some potato with it, I have used some potato wedges in this preparation. So instead of calling it ‘Dim Kosha’ I prefer to call it ‘Haanser Dimer Kosha Jhal’.
