Tel Koi

Tel Koi or Climbing Perch Fish in Mustard Oil Gravy

Tel Koi or Climbing Perch Fish in Mustard Oil Gravy

This recipe is a very popular Bengali "Koi Fish" recipe in a rich, thick, spicy only Mustard Oil based recipe, which should be served with Plain Steamed Rice as Lunch. This recipe come in a regular lunch menu, but for the guests, this is a very good item for lunch.
The Koi I am talking about is also known as climbing perch and belongs to a family of carps. I am usually pretty scared of Koi with its hook like sharp bone and have cooked it only a couple of times. The Koi in packets that I get here is fully cleaned and that gives me much confidence.


  • Koi Fish 6 cleaned and washed
  • Mustard oil 1 cup
  • Onion juice 4 tablespoons (grate a large onion and strain the juice with a clean cheese cloth)
  • Ginger Paste 1 tablespoon
  • Garlic paste 1 tablespoon
  • Green chili 4
  • Tomato Puree 1 tablespoon
  • Bay Leaf 1
  • Cloves 2 /3
  • Cardamom pods 2
  • Cinnamon 1 stick
  • Coriander Powder 1 teaspoon
  • Cumin Powder 1 teaspoon
  • Turmeric powder 1 Tablespoon
  • Red Chilli Powder As per taste
  • Unsweetened Yogurt 2 tablespoons lightly beaten
  • Salt As per taste
  • Sugar As per taste
  • Cilantro (Chopped) To garnish
