The potatoes do not necessarily have to be peeled. Clean the potatoes well and cut them into approx. 1 cm cubes. Peel and quarter the onions and cut into coarse strips. Finely chop the garlic as well. Weigh and prepare the lentils. Prepare the vegetable stock.
Heat the vegetable oil in a medium-sized saucepan. Sweat the onions and garlic in the hot oil. Add the potato cubes and fry a little. Add the curry paste and tomato paste, stir well and let roast a little. Deglaze everything with 300 ml of vegetable stock. Put the lentils in the saucepan and add the spices. Mix everything well. Now simmer everything for 25 minutes over a lower heat.
Use the remaining vegetable broth to achieve the desired consistency. The lenses shouldn`t get too soft.
Prepare rice as a side dish during the cooking time. A fresh leaf salad also goes very well as a side dish. But then the consistency should not be too runny.
