Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Red wine
- Adds acidity and depth of flavour to the sauce base.
- Ketchup
- Provides sweetness, tang, and body as the main sauce base.
- Butter
- Adds fat for a smooth, glossy texture and rounder mouthfeel.
- Vinegar
- Adds sharp acidity that brightens the sweetness of the ketchup.
The step that matters
Heat gently, stirring until well mixed. High heat can scorch the sugars in the ketchup and cause the butter to separate, so gentle heat with constant stirring keeps the sauce smooth and evenly blended.
