Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Cheese Fondu
Ingredients
Directions
The book says “a brisk oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the base
Melt the butter in a saucepan over medium heat.
Stir in the flour.
Add the grated cheese.
Stir for 20 minutes.
Remove from heat.
Let cool.
Add the eggs
Beat the egg yolks.
Add them to the cooled mixture.
Beat the egg whites separately.
Fold them in just before baking.
Bake and serve
Pour the mixture into a greased fondue dish or round cake tin lined with frilled paper.
Bake at 400°F (200°C) for about 45 minutes.
Serve hot, as it will fall when cooling.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks enrich the base while whites, folded in whipped, lighten the mixture and give it rise.
- Butter
- Fat that enriches the base and carries flavour into the cheese mixture.
- Flour
- Starch that thickens the melted butter and cheese into a structured base.
- Grated cheese
- Melts into the base to add savoury flavour and richness.
- Milk
- Adds moisture and softens the batter for a tender texture.
The step that matters
Folding in the egg whites. Whites hold air only when beaten separately and folded in gently just before baking. Stirring them in hard knocks out the air, so the cake rises less and turns dense.
