  • 1.5 teaspoons cumin seeds
  • 1.5 teaspoons black mustard seeds
  • 1.5 teaspoons turmeric powder

Base Ingredients

  • 2 tablespoons cooking oil
  • 1 medium onion, chopped Into small pieces
  • 3 cloves garlic, minced
  • 500 grams sweet potatoes, peeled and cut into cubes
  • 100 grams dried red lentils, rinsed if needed
  • 800 milliliters hot vegetable broth Can adjust up to 1 liter
  • 1 squeeze fresh lemon juice
  • 1 small handful chopped fresh cilantro
  • Sea salt and black pepper, to taste

Instructions
 

Preparation

  • Warm the coriander, cumin, and mustard seeds in a large saucepan over low heat until fragrant and starting to pop.
  • Pour in the oil, add the chopped onion, and cook for about 5 minutes until softened.
  • Stir in the garlic and turmeric, then cook for another 5 minutes.

Cooking

  • Add the diced sweet potatoes and red lentils, mixing well so they are coated with the spiced oil.
  • Pour in 800 ml of hot vegetable broth and bring to a boil.
  • Cover and simmer for 20–25 minutes, or until the sweet potatoes are very soft and the lentils have broken down.
  • Blend the soup until smooth, then add a little more broth if needed to loosen the texture.
  • Return the soup to the pan and reheat gently.
  • Season with salt, pepper, and lemon juice to taste.
  • Stir in most of the cilantro and serve with the remaining cilantro on top.

Notes

For a creamier texture, consider adding a splash of coconut milk after blending. Adjust seasonings to taste.
