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 ↓

Ingredients
Directions
The book says “a cool oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the base
Cut the French milk roll into slices.
Place the slices in a 300°F (150°C) oven until crisp and brown.
Arrange the slices in a well-buttered casserole dish.
Brush the slices with warmed butter mixed with lemon juice.
Assemble and bake
Break a fresh egg onto each slice.
Dust with salt and pepper.
Add a few spoonfuls of cream or thin white sauce.
Bake until the eggs are set.
Serve immediately with baked tomatoes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- French milk roll
- Forms a crisp, absorbent base that holds the egg and sauce.
- Fresh eggs
- Set when baked, forming the soft, rich topping of the dish.
- Butter
- Adds richness and helps the bread brown and crisp.
- Cream or thin white sauce
- Adds moisture and richness, keeping the bread and egg tender while baking.
The step that matters
Bake until the eggs are set. Egg proteins coagulate as they heat, so underbaking leaves the white runny while overbaking makes the yolk dry and rubbery. Watch for opaque whites and a yolk that is just firm.
Swap the tomato
How well each one fits the dish's main ingredients (milk, butter, lemon, egg, pepper, cream):
- Potatofits better
- Asparagusfits better
- Spinachfits better
- Tomatothe original
Fit is the average pairing score against milk, butter, lemon, egg, pepper, cream. Candidates are from the same food group and used in at least 100 recipes.
