1. Bring a pot of salted water to a boil.
2. Slice the carrots into rounds and add them to the boiling water for a quick pre-cooking.
3. Slice the onions and crush the garlic, then sauté them in a skillet with olive oil.
4. Rinse the lentils several times. Add them to the skillet along with the curry. Drain and add the carrots to finish cooking, then add the coriander, salt, and pepper.
5. Cover with water and cook for about 20 minutes over low heat, stirring occasionally.
6. When the lentils and carrots are tender, the soup is ready to be blended.
7. When serving, add 10 to 20 cl of coconut milk or leave it available for each person to adjust according to their taste (more or less sweet), and you can also add some coriander.
