Why it works: Vinegar and mustard are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 14,067 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Cream Sauce
Ingredients
Directions
Make the sauce base
In a saucepan, combine malt vinegar and dry mustard; cook until thick.
Stir in olive oil, sugar, and salt to taste.
Finish the sauce
Beat the whole egg well and add it to the vinegar and mustard mixture; boil for a few minutes, being careful not to let it curdle.
Remove from heat and fold in the stiffly beaten cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Whole egg
- Thickens the sauce as it heats, giving it body and a smooth, rich texture.
- Heavy cream
- Adds richness and a light texture when whipped and folded in.
- Dry mustard
- Contributes sharp, pungent flavour that balances the sweetness and richness.
- Malt vinegar
- Provides acidity that sharpens the flavour and helps the mustard mixture thicken.
- Olive oil
- Adds fat for a smoother mouthfeel and a more rounded sauce.
The step that matters
Boil the egg mixture gently. Egg proteins set when heated, so if the mixture boils too hard or too long it can curdle and turn grainy. Keep it at a gentle boil and stir constantly.
Swap the mustard
How well each one fits the dish's main ingredients (malt, vinegar, olive, sugar, egg, cream):
- Capsicumfits about as well
- Mustardthe original
- Cucumberfits about as well
- Potatofits less well
Fit is the average pairing score against malt, vinegar, olive, sugar, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
