Why it works: Mustard and horseradish match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,832 recipes. Both carry coumarin, which smells sweet, hay. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cream
- Whipped to stiff peaks, it adds a light, airy body to the sauce.
- Mayonnaise
- Adds richness and fat, giving the sauce a smooth, creamy base.
- Mustard
- Adds sharp, pungent flavour that balances the richness of the cream and mayonnaise.
- Grated horseradish
- Adds a pungent, sharp heat that gives the sauce its characteristic bite.
The step that matters
Whip the cream until it forms stiff peaks. Under-whipped cream stays runny and dilutes the sauce, while over-whipped cream turns grainy and can separate. Stopping at stiff peaks gives a thick, stable body that holds when the mayonnaise and horseradish are folded in.
“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.
