Red lentils collapse completely into a soup with no blending, which is why this works without a machine. Twenty-five minutes and it is smooth on its own.
- Rinse the lentils. Into the pan with 1 litre of water, the stock cube and the cumin. Boil, then simmer 20 minutes until they have gone entirely.
- Tomatoes in. Another 5 minutes.
- Salt to taste, then the lemon juice off the heat.
- In a mug or the corner of the pan, heat the oil until it shimmers and add the smoked paprika for ten seconds only: it scorches faster than any other spice here. Pour it over the soup in a stripe.
Do not stir the paprika oil in. The stripe of red on the surface is how the dish is served, and each spoonful takes a different amount.
Serves 4.
