Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓

Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Peel and slice the onion and tomatoes thinly.
Assemble
Stuff the soles with the mixture and place them in a buttered gratin dish.
Layer the onion and tomato slices alternately over the soles.
Sprinkle with salt, pepper, and 1 ounce of butter.
Mix a little Parmesan with the bread crumbs and sprinkle over the top.
Pour 3 tablespoons of tomato sauce around the soles.
Bake
Cover with buttered paper and bake for about 10 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Soles
- Forms the main protein that cooks through gently under the topping.
- Tomatoes
- Add moisture and acidity that keep the fish juicy and balance the richness.
- Spanish onion
- Adds sweetness and aroma as it softens in the oven.
- Parmesan cheese
- Browns on top and adds savory, salty flavor to the crumb crust.
- Bread crumbs
- Form a crisp topping that helps hold moisture in the dish.
- Butter
- Adds fat that carries flavor and helps the topping brown.
The step that matters
Covering the dish before baking. Fish is delicate and dries out or turns tough when overcooked. Covering the dish with buttered paper traps steam so the soles cook gently and stay moist while the topping is set.
