Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Whiting
- Its flesh forms the forcemeat balls, giving a light, tender, delicate texture to the soup.
- Soles
- Their delicate fillets hold their shape and flavour gently in the soup.
- Eel
- Its firm, rich flesh adds body and substance to the fish pieces.
- Chablis or graves wine
- Adds acidity and aromatic depth to the essence as it reduces.
The step that matters
Boil the essence for nearly an hour. Long simmering extracts flavour and gelatine from the bones and trimmings; boiling too hard can cloud the broth and break the delicate fish.
Swap the chervil
How well each one fits the dish's main ingredients (whiting, fish, wine, butter, crayfish, mushroom):
- Thymefits better
- Capersfits better
