Directions

  1. Carefully sort through the water lily pads to remove any dirt or insects. ≈ 3 min
  2. Wash it 2-3 times in cold water, drain it, and finely chop it. ≈ 8 min
  3. Heat the oil in a frying pan or wok; mustard oil adds more flavor.
  4. Lightly toast the cumin and dried chili peppers; remove the chili peppers once they have browned, and set them aside for serving. ≈ 2 min
  5. Sauté the onion and garlic until golden brown.
  6. Add the water chestnuts and green chili peppers. ≈ 3 min
  7. Season well, mix thoroughly, cover, and cook over medium heat: the leaves will release their own moisture.
  8. When they are soft, uncover them, turn up the heat, and stir constantly until all the water has evaporated. ≈ 10 min
  9. Remove from the fire. ≈ 3 min
