Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Melted butter
- Forms the rich base of the sauce and carries the flavour and smooth texture.
- Veal gravy or jelly
- Adds savoury depth and body, helping the butter hold together as a sauce.
- Essence of anchovies
- Adds a salty, savoury depth that rounds out the richness of the butter.
- Mushroom catsup or harvey's sauce
- Can replace the gravy, adding savoury, umami depth to the sauce.
The step that matters
Combining the butter with the gravy or jelly. Melted butter and water-based gravy naturally separate, so whisking steadily while combining helps form a smoother, more cohesive emulsion.
