Soak the lentils in enough water for one night (or about 12 hours).
Drain the water the next morning. Rinse the lentils well, boil them with 2 cups of water and sea salt and cook them for about 15 minutes over medium heat with the lid closed.
Heat the oil in a saucepan and brown the flour in it, stirring. Gradually extinguish with the remaining water. Stir until smooth and bubble on the turned off stove top for 2-3 min. Add the curry, chili spice and cumin and stir in.
Next, stir the sauce into the finished, drained lentils and season with the sour whipped cream.
(*) Cumin
or also called cumin, is a fruit native to the Mediterranean region that is dried and then either crushed or used whole. The essential oils contained in cumin give it its distinctive, intense fragrance and flavor.
