Why it works: Flour and egg are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 106,462 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Bacon Fat Sauce
Ingredients
Directions
Make the sauce
Heat five tablespoonfuls of strained bacon or ham fat in a saucepan.
Add two tablespoonfuls of flour and stir to a smooth paste.
Add one-eighth teaspoonful of paprika and one-third cup of vinegar diluted with one cup of boiling water, stirring constantly.
When the sauce begins to boil, remove to the side of the range and beat in two yolks of eggs.
Add more salt if necessary.
Do not allow the sauce to boil after the eggs are added.
Serve
Chill thoroughly and serve with spinach or dandelion, endive or lettuce.
The sauce may be thinned with cream if too thick.
Nutrition, whole recipe (rough)

Flour and egg barely smell alike, yet cooks put them together in 106,462 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bacon fat
- Provides the fat base that carries the flour and gives the sauce its savory flavour.
- Flour
- Thickens the fat into a paste that gives the sauce body as liquid is added.
- Vinegar
- Adds sharpness that balances the richness of the fat and eggs.
- Eggs
- Yolks enrich and thicken the sauce as they set with gentle heat.
The step that matters
Do not allow the sauce to boil after the eggs are added.. Egg yolks scramble and curdle when overheated, so the sauce turns grainy. Removing it from direct heat before beating in the yolks keeps it smooth and thickened.
“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.
