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 Sauce

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the sauce and add richness as they set gently with the warm mixture.
- Flour
- Combines with the bacon fat to form a roux that thickens the sauce.
- Bacon fat
- Carries flavor and gives the sauce a smooth, rich body.
- Vinegar
- Adds acidity that sharpens the sauce and balances the richness of the fat.
The step that matters
Do not allow the sauce to boil after adding the eggs. Egg yolks are proteins that scramble and curdle when overheated, so the sauce can turn grainy. Keep it warm but below boiling once the yolks go in.
