Why it works: Parsley and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 14,037 recipes mention both. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Sole Au Gratin
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C).
Butter a gratin dish.
Sprinkle half of the parsley, shallot, and mushrooms on the dish, along with a little lemon juice, pepper, and salt.
Lay the sole in the dish, skin side down, notched to prevent contracting while cooking.
Remove the dark skin from the sole.
Bake and serve
Sprinkle the remaining parsley, shallot, and mushrooms over the sole.
Add a few pieces of butter on top.
Bake for 10 to 15 minutes.
Serve in the dish it was cooked in, with the glaze poured over it.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sole
- Forms the main body of the dish and cooks gently in the dish's juices.
- Butter
- Adds fat and richness, helping the fish stay moist and the top brown.
- Button mushrooms
- Release moisture and savoury flavour as they cook under the fish.
- Shallot
- Adds a mild onion-like sweetness and aroma that softens during baking.
- Good glaze
- Adds a rich, glossy finish and concentrated flavour when poured over the fish.
The step that matters
Notching the sole before baking. Notching the skin stops the fish from contracting and curling as it heats, so it bakes flat and evenly in the dish.
