Ingredients

Instructions

  1. Step 1: Pat salmon dry and cut into 1-inch cubes; season with 1/2 teaspoon salt. Dice potatoes into 1/2-inch cubes and set aside.
  2. Step 2: Heat 2 tablespoons vegetable oil in a heavy pot over medium heat. Add 1/4 cup mustard seeds and 1/2 teaspoon cumin seeds, stirring until seeds pop and sizzle (about 2 minutes).
  3. Step 3: Add 1 large chopped onion and cook until golden brown (8-10 minutes), stirring frequently to prevent burning.
  4. Step 4: Stir in 3 minced garlic cloves, 1 tablespoon minced ginger, and 1 teaspoon turmeric powder; cook for 1 minute until fragrant.
  5. Step 5: Add 1/4 cup tomato puree and cook for 3 minutes until thickened, then stir in 1 cup water and 2 tablespoons prepared mustard.
  6. Step 6: Add potato cubes and salmon cubes, stirring gently to coat. Bring to a simmer, then cover and cook for 20 minutes until potatoes are tender and salmon is cooked through, stirring once halfway.
  7. Step 7: Season with remaining salt and garnish with fresh cilantro before serving.
