Ingredients
Lemons: Their juice provides the vibrant freshness that gives the sauce its characteristic tangy flavor. Choose fresh lemons for best quality. Limes can be substituted, although the flavor will be slightly different.
Crème fraîche: It adds creaminess and a slight acidity that balances the lemon. Greek yogurt can be substituted for a lighter version, although the texture will be different.
Butter: It forms the base of the roux, adding richness and a silky texture to the sauce. Salted butter can be used, adjusting the final seasoning.
Mustard: It adds depth and a slight tang that enhances the overall flavor. Dijon mustard is ideal, but any mild mustard will do.
Flour: This thickens the sauce by forming a roux with the butter. For a gluten-free version, cornstarch can be substituted, diluted with a little water.
Salt: Essential for enhancing the flavors and ensuring the sauce’s balance. Adjust to your taste.
Pepper: It adds a slight heat and complexity. Freshly ground black pepper is ideal for its aromatic touch.
Chopped parsley (optional): It adds a touch of fresh color and a light herbaceous note to the final dish. You can omit it if preferred.
