Why it works: Capers and shallot match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 405 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Grill Sauce
Ingredients
Directions
Make the sauce
In a saucepan, combine the gravy and butter over low heat.
Mix the flour with a little water to form a paste, then add it to the saucepan.
Stir in the mushroom or walnut ketchup, lemon juice, mustard, capers, black pepper, grated lemon rind, essence of anchovies, minced shallot, and chili vinegar.
Simmer the mixture for a few minutes until thickened.
Serve
Pour some sauce over the grilled dish and serve the rest in a sauce boat.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gravy
- Forms the liquid base of the sauce and carries the other flavours.
- Butter
- Adds fat and richness, giving the sauce a smooth, glossy mouthfeel.
- Flour
- Thickens the sauce as it simmers, giving it body.
- Mushroom or walnut ketchup
- Adds concentrated savoury depth and umami to the sauce.
- Lemon juice
- Adds acidity that brightens the rich gravy and butter.
The step that matters
Simmering until thickened. Flour needs to simmer for a few minutes to cook out its raw starchy taste and reach full thickening power. Stopping early leaves the sauce pasty, while boiling hard or too long can make it gluey and reduce it too far.
