Step 1
- a.Boil and Fry the Eggs
- b.Place eggs in a saucepan and cover with cold water by at least an inch. Bring to a rolling boil, then reduce heat and simmer for 10 minutes for hard-boiled eggs.
- c.Immediately transfer the eggs to an ice bath to stop the cooking process and make peeling easier. Once cool, peel the eggs.
- d.Gently make 2-3 shallow slits on the surface of each peeled egg. This helps them absorb the gravy's flavor.
- e.In a pan or kadai, heat 1 tbsp of mustard oil over medium heat. Add the boiled eggs, a pinch of salt, and 1/4 tsp of the turmeric powder. Sauté for 2-3 minutes, turning gently, until they are lightly golden and blistered. Remove and set aside.

Step 2
- a.Prepare the Tempering (Phodon)
- b.In the same pan, add the remaining 3 tbsp of mustard oil and heat until it's slightly smoking. This removes the raw pungency of the oil.
- c.Reduce the heat to low. Add the bay leaf, cinnamon stick, lightly crushed green cardamom pods, and cloves. Sauté for about 30-45 seconds until they become fragrant.

Step 3
- a.Sauté the Masala (Kosha)
- b.Add the finely chopped onions to the pan. Sauté on medium heat for 8-10 minutes, stirring occasionally, until they turn a deep golden brown. Be patient, as this caramelization is crucial for the flavor.
- c.Add the ginger and garlic paste. Cook for 1-2 minutes until the raw aroma disappears.
- d.Stir in the tomato puree and cook for 3-4 minutes until it thickens and the oil starts to separate slightly.
- e.Lower the heat and add the remaining turmeric powder, Kashmiri red chili powder, cumin powder, coriander powder, and salt. Mix everything well.
- f.Now begins the 'kosha' process. Sauté this masala mixture on low-medium heat for 5-7 minutes, stirring frequently. Scrape the bottom of the pan. The masala will darken, become a cohesive mass, and you'll see oil clearly separating from the sides.

Step 4
- a.Simmer the Curry
- b.Pour in 1.5 cups of hot water and add the sugar. Stir well to combine, ensuring you scrape any flavorful bits from the bottom of the pan.
- c.Bring the gravy to a gentle boil over medium heat.
- d.Gently slide in the fried eggs and the slit green chilies.
- e.Cover the pan, reduce the heat to low, and let it simmer for 5-7 minutes. This allows the eggs to soak up the flavors and the gravy to thicken to the desired consistency.

Step 5
- a.Finish and Serve
- b.Turn off the heat. Sprinkle the garam masala powder over the curry and give it a final, gentle stir.
- c.Garnish with freshly chopped coriander leaves.
- d.Let the Dimer Kosha rest, covered, for at least 10 minutes before serving. This helps the flavors to meld and deepen.
- e.Serve hot with steamed rice, luchi (puffed bread), or porota (paratha).
What to keep in mind.
5 tips from the recipe — small details that make a real difference to the final dish.
- 1Using mustard oil is key for the authentic Bengali flavor. Always heat it until it's lightly smoking to mellow its pungent taste.
- 2The 'kosha' or slow-sautéing of the onion and spice mixture is the most critical step. Do not rush it; cook until oil separates for a rich, deep-flavored gravy.
- 3Making shallow slits in the boiled eggs is a simple trick that allows them to absorb the maximum flavor from the curry.
- 4The small amount of sugar is a traditional Bengali touch that balances the tanginess of the tomatoes and rounds out the spices.
- 5For a heartier curry, you can add one large potato, peeled, cubed, and fried until golden, along with the eggs in Step 4.

Ingredient Addition
For a heartier version, add one large potato, cubed and fried until golden. Add it to the gravy along with the eggs to simmer.
Flavor ProfileFlavor Profile
For a richer, creamier gravy, you can add 1-2 tablespoons of well-whisked plain yogurt (curd) after the tomato puree has cooked down. Cook on low heat to prevent curdling.
Spice LevelSpice Level
To increase the heat, add a pinch of regular red chili powder along with the Kashmiri variety, or increase the number of slit green chilies.

If mustard oil is unavailable, you can use a neutral vegetable oil like sunflower or canola oil, though the authentic flavor will be milder.
