Why it works: Lemon and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
French Fish Stew
Ingredients
Directions
Make the gravy
Heat lard in a good-sized stewpan until hot.
Add the chopped onion and fry until brown.
Dust in the flour and cook until browned.
Pour in the boiling water and season with salt, black pepper, red pepper, and garlic.
Simmer the fish
Add the fish to the stewpan, ensuring it is covered with gravy.
Cover and let it simmer slowly until the fish is nearly done.
Add the claret wine and Madeira without stirring; just shake to mix.
Let it simmer for a few more minutes until ready to serve.
Serve
Carefully remove the fish and place it on a dish.
Pour the gravy over the fish and garnish with lemon slices, parsley, and celery.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lard
- Fat that fries the onion and carries flavour into the gravy.
- Flour
- Thickens the gravy as it cooks with the fat and liquid.
- Onion
- Browns in the fat to add savoury sweetness and depth to the gravy.
- Fish
- Main protein that cooks gently in the simmering gravy until just done.
- Claret wine
- Adds acidity and fruity aroma to the gravy.
- Madeira
- Adds sweetness and rich, caramelised aroma to the gravy.
The step that matters
Adding the wine and Madeira without stirring. Stirring a simmering stew that contains flaking fish breaks the fish apart. Gently shaking the pan mixes the liquids while keeping the fish intact and tender.
