🥗 Ingredients
The Star Fish
- 4-6 pieces Hilsa (Ilish) Fish Steaks (cut into 1-inch thick rounds, cleaned thoroughly)
- 1/2 teaspoon Turmeric Powder (for initial marination)
- 1/2 teaspoon Salt (to taste)
The Pungent Mustard Paste
- 2 tablespoons Black Mustard Seeds (soaked in warm water for 15 minutes)
- 1 tablespoon Yellow Mustard Seeds (soaked in warm water for 15 minutes)
- 1/4 cup Fresh Grated Coconut (adds sweetness and body to the gravy)
- 4-5 pieces Green Chilies (adjust based on heat preference)
- 1/4 teaspoon Salt (added while grinding to prevent bitterness)
- 2-3 tablespoons Water (for a smooth paste)
The Gravy & Tempering
- 3 tablespoons Plain Yogurt (Curd) (whisked until smooth)
- 1/2 teaspoon Turmeric Powder
- 3-4 tablespoons Virgin Mustard Oil (essential for the authentic pungent aroma)
- 4 pieces Whole Green Chilies (slit lengthwise)
- 1/4 teaspoon Sugar (to balance the acidity)
👨🍳 Instructions
-
1
Gently wash the Hilsa steaks and pat them dry with paper towels. Rub them with 1/2 teaspoon turmeric and 1/2 teaspoon salt, then set aside for 10-15 minutes.
-
2
Drain the soaked black and yellow mustard seeds. Place them in a blender or traditional grinding stone with the grated coconut, 2 green chilies, and a pinch of salt.
-
3
Grind the mixture into a very smooth, thick paste. Add a splash of water only if necessary to keep the consistency thick.
-
4
In a large stainless steel tiffin box or a heat-proof glass container with a tight lid, combine the mustard-coconut paste with the whisked yogurt.
-
5
Add 1/2 teaspoon turmeric powder, sugar, and 2 tablespoons of raw mustard oil to the paste. Mix thoroughly until the marinade is glossy and uniform.
-
6
Carefully place the marinated fish steaks into the tiffin box. Turn each piece to ensure they are completely coated in the thick mustard gravy.
-
7
Arrange the slit green chilies on top of the fish and drizzle the remaining 1-2 tablespoons of mustard oil over everything for that signature 'jhal' (pungency).
-
8
Close the lid of the tiffin box securely. If your lid is loose, wrap the top with aluminum foil before closing to ensure no steam enters the container.
-
9
Prepare a steamer or a deep pan with about 2 inches of water. Place a small stand or ring at the bottom of the pan.
-
10
Place the tiffin box on the stand. Ensure the water level reaches only halfway up the sides of the box; it should not submerge the lid.
-
11
Cover the pan with a heavy lid and steam on medium-low heat for 15-20 minutes. You should hear a gentle simmering sound.
-
12
Turn off the heat and let the container sit undisturbed in the steamer for another 10 minutes. This 'resting' period allows the flavors to penetrate the fish deeply.
-
13
Carefully remove the box, open the lid, and check if the fish is opaque and flaky. The oil should have separated and risen to the top of the golden gravy.
💡 Chef's Tips
Always add a pinch of salt while grinding mustard seeds to prevent the paste from turning bitter. Use a mix of black and yellow mustard seeds; black provides the heat, while yellow provides a mellow sweetness and volume. Never skip the raw mustard oil at the end; it is the soul of this dish and provides the characteristic 'nasal hit'. If Hilsa is unavailable, you can use Salmon or Mackerel steaks, though the flavor profile will significantly change. Handle the fish gently after steaming as Hilsa is very delicate and can break easily once cooked.
🍽️ Serving Suggestions
Serve piping hot alongside a mound of fragrant, long-grain Basmati or Gobindobhog steamed rice. A side of simple roasted potatoes (Alu Bhaja) provides a lovely crunch to contrast the soft fish. Pair with a wedge of Gondhoraj lime for a burst of citrus aroma that cuts through the richness of the fish oil. Enjoy with a glass of chilled tender coconut water or a light lime soda to balance the pungent mustard heat. Traditionally eaten as the centerpiece of a formal Bengali lunch, following a bitter starter like Shukto.
