Chef's tips
Castelluccio lentils have tender skins developed from the high-altitude climate, so never soak them before cooking. Add salt only near the end of cooking to ensure the skins remain soft. Use a peppery, green Umbrian extra-virgin olive oil at the table for an authentic finish.
Ingredient substitutions
- Castelluccio di Norcia lentils → small brown mountain lentils or Puy green lentils, though cooking time will increase by ten minutes
- canned chopped tomatoes → one tablespoon of double-concentrated tomato purée dissolved in warm water
Storage
Store cooled soup in an airtight container in the refrigerator for up to three days.
Reheating
Reheat gently in a saucepan over medium-low heat, adding a splash of water if the broth has thickened.
Common mistakes to avoid
- •Soaking the lentils beforehand, which makes the delicate skins split and turns the soup mushy.
- •Salting the broth at the beginning, which can toughen the lentil skins.
- •Boiling rapidly rather than simmering gently, which breaks the lentils apart.
