Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Baked Tuna Fish
Ingredients
Directions
The book says “a hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Mix the filling
Preheat the oven to 350°F (175°C).
In a bowl, combine the bread crumbs, lemon juice, melted butter, salt, and pepper.
Chop the tuna fish finely and mix it with the egg yolks and seasoning.
Fold in the beaten egg whites until well combined.
Bake
Transfer the mixture to a buttered baking tin.
Bake for 35 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped air gives the mixture lightness and helps it rise in the oven.
- Egg yolks
- Bind the filling and add richness and a set structure when baked.
- Soft bread crumbs
- Absorb liquid and give the mixture body so it holds together.
- Melted butter
- Adds fat for a softer texture and rich flavour.
- Lemon juice
- Adds acidity that brightens the flavour and balances the richness.
The step that matters
Fold in the beaten egg whites. Egg whites hold air that gives lift. Folding gently keeps that air in the mixture; stirring or beating after adding them deflates the foam, leaving a denser, flatter bake.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
