Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Anchovies
- Break down during boiling to give the ketchup its savory, salty depth.
- Shallots
- Add aromatic sweetness and body to the liquid as they cook down.
- Red wine
- Adds acidity and color, and its tannins and sugars deepen the flavor as it reduces.
- White wine
- Adds acidity and lightens the flavor while helping the liquid reduce.
The step that matters
Boil until reduced to 1 quart. Boiling concentrates the liquid and flavors, so the ketchup stays thin enough to pour yet gains depth. Reducing too little leaves it weak and watery; reducing too far makes it harsh and overly salty.
Swap the mace
How well each one fits the dish's main ingredients (shallot, horseradish, white wine, red wine, lemon, anchovy, clove):
- Thymefits better
- Capersfits better
- Tarragonfits better
- Macethe original
