crème fraîche

The small amount of crème fraîche used in the watercress sauce provides a creamy texture and tangy flavor. Although it is high in saturated fats, moderate consumption can be part of a balanced diet.


Watercress is a nutrient-dense leafy green that is rich in vitamins A, C and K. It is also rich in antioxidants and minerals such as calcium and iron. Including watercress in your diet can support bone health, boost the immune system and promote healthy digestion.
