Hilsa Bhapa

About This Recipe

Ilish (hilsa) is Bangladesh's national fish and the most prized ingredient in Bengali cuisine. Bhapa means 'steamed', and this technique gently cooks the fatty, oily hilsa fillets within a vivid yellow-green paste of ground mustard seeds, fresh coconut, green chillies, and turmeric. The result is a deeply aromatic, intensely flavoured dish that showcases the fish's natural richness. Hilsa has a distinctive texture — oily, tender, and with many fine bones — and a flavour unlike any other fish, often described as smoky and herbal. The dish is traditionally cooked sealed in a tiffin box or aluminium container set over a pot of boiling water, making it completely hands-off once assembled.

Ingredients

Serves 4

• 600 ghilsa (ilish) fish steaks(or mackerel/salmon if unavailable)
• 3 tbspblack mustard seeds
• 3 tbspyellow mustard seeds
• 50 gfresh coconut(grated (or 3 tbsp desiccated))
• 5–6green chillies(2 blended, rest slit)
• ½ tspground turmeric
• 1 tspsalt
• 3 tbspmustard oil(plus extra to finish)
• 2 tbspnatural yogurt

Instructions

1. 1

   Make mustard paste

   Soak black and yellow mustard seeds in 4 tbsp water for 10 minutes. Blend with coconut, 2 green chillies, turmeric, salt, and a splash of water to a smooth, thick paste.

2. 2

   Coat the fish

   Mix the mustard paste with yogurt and 2 tbsp mustard oil. Add fish steaks and coat thoroughly. Add the slit green chillies.

   Resting the coated fish for 10–15 minutes allows the mustard to penetrate the flesh.

3. 3

   Seal and steam

   Transfer fish and paste to a tight-lidded box or a small baking dish wrapped tightly with foil. Place over a pot of simmering water (or in a steamer). Steam for 18–20 minutes until fish is just cooked through.

4. 4

   Finish and serve

   Open carefully (steam is hot). Drizzle with the remaining mustard oil. Serve immediately with steamed white rice.

Variations

• •

  Use rohu or catla fish if hilsa is unavailable — the paste works beautifully with most freshwater fish.

• •

  Substitute mustard oil with extra virgin olive oil in a pinch.

• •

  Add a few curry leaves for a South Indian twist.

• •

  Vegetarian: swap the protein for roasted king oyster mushrooms, smoked tofu or cooked chickpeas — adjust seasoning slightly upward to compensate.

Storage

Best eaten immediately. Keeps in the fridge up to 1 day but the mustard flavour becomes more intense.
