Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Provide the main body and savoury flavour of the ketchup.
- Coarse sea salt
- Draws moisture out of the mushrooms and preserves the liquid through the long standing.
The step that matters
Salting and standing the mushrooms. Enough salt must be fully mixed in so it draws out juice and inhibits spoilage. Stirring during the three days helps the salt penetrate evenly and keeps the mixture from spoiling at the surface.
Swap the mace
How well each one fits the dish's main ingredients (mushroom, ginger, allspice, pepper, brandy):
- Clovefits better
- Cinnamonfits better
- Thymefits better
- Macethe original
Fit is the average pairing score against mushroom, ginger, allspice, pepper, brandy. Candidates are from the same food group and used in at least 100 recipes.
