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 ↓
Shad, with Sorrel
Ingredients
Directions
Prepare
Pare and scale the shad.
Marinate the shad in oil, lemon, parsley roots, and onion for as long as possible.
Cook
Place the shad in a buttered stewpan with white wine, mushroom liquor, and a bouquet.
Mince the sorrel finely and add it to the stewpan with the fish, salt, and pepper.
Cover the stewpan and cook on low heat for at least 2 hours.
Finish and serve
Arrange the shad on a dish.
Add white roux to the juice and thicken the sauce.
Pour the sauce over the fish when serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shad
- Is the main protein, cooked gently until it becomes tender and flakes easily.
- Sorrel
- Its acidity adds a sharp, lemony flavour that balances the rich fish and sauce.
- White roux
- Flour and fat thicken the cooking juices into a smooth, body-rich sauce.
- White wine
- Adds acidity and moisture to the cooking liquid, lending flavour to the sauce.
- Mushroom liquor
- Contributes savoury, earthy flavour to the cooking juices that form the sauce.
The step that matters
Cook on low heat for at least 2 hours. Gentle, covered heat lets the fish cook through slowly and stay moist while the bones and connective tissue soften. Rapid boiling would toughen the flesh and break it apart.
Swap the onion
How well each one fits the dish's main ingredients (lemon, parsley, white wine, mushroom, sorrel, pepper):
- Shallotfits better
