📝 About This Recipe

Step back into the golden age of steam travel with this iconic Anglo-Indian masterpiece, originally served in the first-class dining cars of the Indian Railways. This curry is celebrated for its unique fusion of British sensibilities and bold Indian spices, featuring a signature tang from vinegar and a velvety richness from coconut milk. It is a nostalgic, mildly spiced journey that showcases tender mutton and golden potatoes in a vibrant, sunset-hued gravy.

🥗 Ingredients

The Meat and Marinade

  • 2 lbs Mutton (Goat or Lamb shoulder) (cut into 1.5-inch bone-in chunks)
  • 2 tablespoons Ginger-Garlic Paste (freshly ground)
  • 1/2 teaspoon Turmeric Powder
  • 1 teaspoon Salt (or to taste)

Whole Spices (The Tempering)

  • 4 tablespoons Vegetable Oil or Ghee (canola or sunflower oil works well)
  • 1 piece Cinnamon Stick (2-inch stick)
  • 4 pieces Green Cardamom Pods (lightly crushed)
  • 4-5 pieces Cloves
  • 2 pieces Bay Leaf (dried)

The Curry Base

  • 3 medium Red Onions (very finely sliced)
  • 2 large Potatoes (peeled and quartered)
  • 1.5 tablespoons Kashmiri Red Chili Powder (for vibrant color and mild heat)
  • 1 tablespoon Coriander Powder
  • 1 teaspoon Cumin Powder (toasted)
  • 1 tablespoon White Vinegar (the secret Anglo-Indian ingredient)
  • 1/2 cup Coconut Milk (thick, full-fat)
  • 1/4 cup Fresh Cilantro (chopped for garnish)

👨‍🍳 Instructions

  1. 1

    In a large bowl, toss the mutton chunks with the ginger-garlic paste, turmeric, and salt. Set aside to marinate for at least 20 minutes.

  2. 2

    Heat the oil or ghee in a heavy-bottomed pot or Dutch oven over medium-high heat. Add the quartered potatoes and fry until the edges are golden brown. Remove and set aside.

  3. 3

    In the same oil, add the cinnamon, cardamom, cloves, and bay leaves. Sauté for 30 seconds until they become fragrant and start to sizzle.

  4. 4

    Add the sliced onions to the pot. Sauté for 12-15 minutes, stirring frequently, until they are a deep caramel brown. Do not rush this; the onions provide the color and sweetness of the gravy.

  5. 5

    Add the marinated mutton to the pot. Turn the heat to high and sear the meat for 5-7 minutes until it loses its raw pink color and begins to brown.

  6. 6

    Lower the heat to medium. Stir in the Kashmiri chili powder, coriander powder, and cumin powder. Add a splash of water if the spices stick to the bottom.

  7. 7

    Pour in 2 cups of hot water. Bring to a boil, then reduce the heat to low. Cover with a tight-fitting lid and simmer for 45-50 minutes, or until the mutton is 80% tender.

  8. 8

    Add the fried potatoes back into the pot. Stir in the white vinegar, which acts as a tenderizer and provides the signature 'Railway' tang.

  9. 9

    Continue to simmer covered for another 15 minutes until both the mutton and potatoes are fork-tender.

  10. 10

    Slowly pour in the coconut milk while stirring gently. Simmer uncovered for 5 minutes to allow the gravy to thicken and become silky.

  11. 11

    Taste and adjust salt if necessary. Turn off the heat and let the curry rest for 10 minutes—this allows the oils to rise to the surface (the 'rogon').

  12. 12

    Garnish generously with fresh cilantro and serve hot.

💡 Chef's Tips

Always use bone-in mutton for this recipe; the marrow adds a depth of flavor that boneless meat cannot replicate. If the mutton is particularly tough, you can use a pressure cooker or Instant Pot to speed up the process (about 15-20 minutes under pressure). Don't skip frying the potatoes separately; it prevents them from turning mushy and helps them hold their shape in the gravy. The secret to the authentic color is the Kashmiri chili powder—it provides a brilliant red hue without making the dish overly spicy. For the best flavor, make this curry a few hours in advance or even the day before; the spices mellow and penetrate the meat beautifully over time.

🍽️ Serving Suggestions

Serve with hot, buttered Pav (Indian bread rolls) or crusty French baguettes to soak up the gravy. Pair with fragrant Steamed Basmati Rice or a simple Jeera (Cumin) Rice. Accompany with a side of sharp pickled onions and a wedge of lime for extra brightness. A simple cucumber and tomato raita (yogurt dip) helps balance the richness of the coconut milk. For a traditional touch, serve with a side of 'Yellow Rice' (Turmeric-tinted pilaf).
