Bihari Maach (Fish Curry)

Bihari Maach (fish curry) is a cornerstone of Mithila cuisine and a daily staple in the Gangetic plains of North Bihar. Freshwater fish — primarily Rohu (Labeo rohita), Katla, or Singhara (catfish) — caught fresh from the Ganga, Gandak, Kosi, and Bagmati rivers, are marinated in turmeric and salt, shallow-fried in mustard oil until a golden crust forms, then slowly simmered in a pungent, tangy gravy. The gravy is built on a base of mustard paste (ground fresh yellow mustard seeds), onion, tomatoes, green chilies, and the iconic Panch Phoran tempering. The raw mustard oil imparts a distinctive, sharp "jhanjh" (pungency) that is characteristic of all authentic Bihari fish preparations. Fish is considered auspicious in Mithila and is an essential part of weddings, festivals, and offerings.

Fish pieces are marinated with turmeric and salt for 15 minutes, then shallow-fried in hot mustard oil until golden and slightly crispy on both sides. In the same pan, Panch Phoran is added to hot mustard oil and tempered until fragrant. Onions are sautéed golden, then ginger-garlic paste, mustard paste, and tomatoes are added and cooked into a thick masala. Fish pieces are added to the gravy and simmered covered on low heat for 15–20 minutes until the fish absorbs all flavors.

Served in a deep bowl or on banana leaves (at traditional functions). Always accompanied by steamed rice (bhaat). Never eaten with roti in traditional Mithila homes.
