Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Melts to form the fat base that carries the mustard and pepper flavours.
- Prepared mustard
- Adds sharp, acidic flavour and helps emulsify the butter into a smooth sauce.
- Black pepper
- Contributes sharp, aromatic heat that seasons the sauce.
- Cayenne pepper
- Adds clean, lingering heat to the sauce.
The step that matters
Keep the heat low when melting the butter. If the butter gets too hot it can separate or scorch, so the sauce loses its smooth, thick custard-like texture and may taste burnt.
