Hilsha Fry Recipe

Prepare fish

Rinse the hilsha pieces under cold water, pat dry thoroughly with paper towels. If there are extra bones, leave them — hilsha is traditionally served with bones for flavor. Score each side of the steaks lightly (2–3 shallow diagonal cuts) to help marinade penetrate.

Apply turmeric powder and 1 tsp salt evenly over both sides of the fish. If using yogurt, mix yogurt with 1 tbs mustard oil and spread a thin layer over the pieces. Let marinate for 20–30 minutes at room temperature (no longer than 30 minutes to avoid over-tenderizing).

In a shallow bowl, combine gram flour (besan), rice flour (if using), red chili powder, remaining 0.5 tsp salt, black pepper and a pinch of sugar. Mix until even. Adjust seasonings to taste.

Lightly dust each marinated hilsha piece with the dry coating on all sides, pressing gently so the flour adheres. Shake off excess. The coating should form a thin layer — not a heavy batter — to preserve the fish's delicate texture.

Have green chilies slit, ginger and garlic (if using) ready. Chop coriander and prepare lemon wedges. These will be added near the end and used for serving.

Heat a heavy skillet or nonstick pan over medium-high heat. Add the mustard oil and neutral oil blend. Heat until shimmering and very hot; if using mustard oil, you may want to heat until faint wisps of smoke then let it cool for 30 seconds to reduce harshness. Test by dropping a small pinch of coating — it should sizzle immediately.

Reduce heat to medium. Carefully place coated hilsha pieces in the pan without crowding (work in batches if necessary). Fry for 3–4 minutes on the first side without moving, until the coating is golden brown and releases easily from the pan.

Flip gently using a spatula and cook the other side 3–4 minutes. Timing depends on thickness; aim for an internal opaque color and cooked-through flesh. Avoid overcooking — hilsha becomes dry quickly.

During the last minute of frying, add the slit green chilies, julienned ginger and crushed garlic to the pan. Toss gently in the oil to blister and perfume the fish. Spoon some hot oil over the hilsha once or twice to baste.

Transfer fried hilsha to a plate lined with paper towel to absorb excess oil. Sprinkle chopped coriander over the fish and serve immediately with lemon wedges on the side.
