A beloved Zanzibar street-food classic, this tangy, golden, gently spiced soup is poured over crispy fried potato sticks, hard-boiled eggs, fluffy bread, and a bright tomato-tamarind chutney. The broth is thickened with chickpea and lentil flours, perfumed with warm coastal spices, and finished with a sharp squeeze of lime for that signature bite.

Ingredients

For the spice paste

  • 1 medium yellow onion, roughly chopped
  • 4 garlic cloves
  • 1 (1-inch) piece fresh ginger, peeled
  • 2 green chilies, seeds removed for milder heat
  • 1 tablespoon ground coriander
  • 1 teaspoon ground cumin
  • 1 teaspoon ground turmeric
  • 1/2 teaspoon ground black pepper

For the soup base

  • 2 tablespoons vegetable oil
  • 1/2 cup chickpea (gram) flour
  • 1/3 cup red lentils, rinsed and drained
  • 6 cups water
  • 2 Roma tomatoes, finely chopped
  • 1 tablespoon tamarind paste
  • 1 teaspoon salt, plus more to taste
  • 1 bay leaf

For the serving mix

  • 2 medium russet potatoes, peeled and cut into thin matchsticks
  • 1 1/2 cups vegetable oil, for frying
  • 4 large eggs, hard-boiled and peeled
  • 4 slices crusty white bread or 4 small chapatis, torn
  • 1 large lime, cut into wedges

For the quick tomato-tamarind chutney

  • 1 small tomato, finely diced
  • 1 small red onion, finely diced
  • 1 tablespoon tamarind paste
  • 1/4 teaspoon chili powder
  • 1 tablespoon chopped cilantro
  • Pinch of salt

Directions

  1. Make the spice paste: combine the onion, garlic, ginger, green chilies, ground coriander, cumin, turmeric, and black pepper in a small blender with 3 tablespoons of water. Blend into a smooth, vibrant paste.
  2. Heat the vegetable oil in a large heavy pot over medium heat. Add the chickpea flour and stir constantly for 3 to 4 minutes until it turns a deep golden color and smells toasty. Whisk in the red lentils to coat them in the flour.
  3. Add the spice paste to the pot and cook, stirring, for 4 to 5 minutes until the oil begins to separate from the mixture and the raw onion smell disappears.
  4. Pour in the 6 cups of water, scraping the bottom of the pot to release any browned bits. Add the chopped tomatoes, tamarind paste, salt, and bay leaf. Bring to a boil, then reduce heat and simmer uncovered for 25 minutes, stirring occasionally, until the lentils are completely soft and the soup has thickened to a creamy, pourable consistency similar to heavy cream.
  5. While the soup simmers, prepare the mix: heat the 1 1/2 cups of oil in a deep skillet to 350 degrees F. Fry the potato matchsticks in small batches for 3 to 4 minutes until crisp and golden. Drain on paper towels and sprinkle lightly with salt.
  6. Make the chutney by stirring together the diced tomato, red onion, tamarind paste, chili powder, cilantro, and salt in a small bowl. Set aside.
  7. Taste the soup and adjust salt and tamarind for a balance of savory and tangy. Remove the bay leaf and discard.
  8. To serve, place a torn piece of bread in the bottom of each bowl. Top with a generous handful of crispy potato sticks and a halved or quartered hard-boiled egg. Ladle the hot soup over everything, spoon some chutney alongside, and finish with a squeeze of fresh lime.
  9. Serve immediately while the soup is piping hot and the potatoes stay crisp. Encourage diners to break the bread and egg into the broth as they eat.

Cook’s Notes

  • For the most authentic flavor, source whole spices and toast them yourself before grinding; freshly toasted cumin and coriander make a remarkable difference in the broth.
  • If tamarind paste is unavailable, substitute with 2 tablespoons of fresh lime juice plus 1 teaspoon of brown sugar for a similar sweet-sour tang.
  • The soup base can be made up to 3 days ahead and refrigerated; just thin it with a splash of water when reheating, as it thickens considerably as it cools.
  • For a vegetarian-friendly version, skip the eggs and add cubes of fried halloumi or extra potato sticks for a satisfying protein boost.
  • Fry the potatoes at the very last minute so they stay audibly crisp when the hot soup hits them; soggy potatoes are the only real pitfall of this dish.
