Why it works: Mustard and cucumber match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 2,281 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Wow Wow Sauce for Stewed or Bouilli Beef
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the sauce
Melt the butter in a saucepan over medium heat.
Stir in the flour and cook for 1 minute.
Gradually add the beef broth, stirring constantly until thickened.
Mix in the vinegar, mushroom ketchup or port wine, and mustard.
Let the sauce simmer until it reaches your desired thickness.
Finish and serve
Add the parsley and pickles, warming them through.
Serve the sauce over the beef or in a sauce tureen.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the sauce and carries flavour as the base of the roux.
- All-purpose flour
- Thickens the broth into a smooth sauce when cooked with the butter.
- Beef broth
- Forms the liquid body of the sauce and supplies savoury meaty flavour.
- Vinegar
- Adds acidity that sharpens and balances the richness of the sauce.
- Mushroom ketchup or port wine
- Adds deep savoury and fruity notes that give the sauce its character.
- Prepared mustard
- Adds sharpness and a hint of heat that lifts the savoury flavours.
The step that matters
Adding the broth gradually while stirring constantly. Adding liquid slowly to the hot butter and flour mixture and stirring keeps starch dispersed, so the sauce thickens smoothly instead of forming lumps.
