Why it works: Ham and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 2,536 recipes. Both carry 2-acetyl-1-pyrroline, which smells popcorn, roasted. The science ↓
Ham Toast
Ingredients
Directions
The book says “a very hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the topping
Chop the ham very fine.
Mix the ham with the egg yolk and enough cream to moisten.
Season with salt and cayenne pepper.
Assemble and brown
Toast the bread slices until golden.
Place a mound of the ham mixture on each slice.
Brown the surface quickly in a hot oven at 400°F (200°C) or before an open fire.
Serve
Serve hot or cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ham
- Provides the savoury meat base and most of the flavour of the topping.
- Egg yolk
- Binds the chopped ham into a cohesive mound and adds richness.
- Cream
- Moistens the ham so the topping stays tender rather than dry.
- Bread
- Forms the crisp base that holds the topping.
The step that matters
Brown the surface quickly in a hot oven. The ham is already cooked, so the goal is only to brown the surface. Too long or too cool and the egg yolk can dry out or cook through, while the bread softens under the moist topping. A hot oven browns the surface quickly, keeping the topping moist inside.
