Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Fresh mushrooms
Provide the main body and savoury flavour of the ketchup once their juice is extracted.
Coarse sea salt
Draws moisture out of the mushrooms and preserves the liquid against spoilage.
Allspice
Adds warm, aromatic spice notes that round out the savoury base.

The step that matters

Salting and resting the mushrooms. Salt must be layered evenly and the mushrooms stirred during the three days so salt draws out juice uniformly and prevents spoilage before cooking.

Swap the mace

How well each one fits the dish's main ingredients (mushroom, allspice, ginger):

  1. Clovefits better
  2. Cinnamonfits better
  3. Thymefits better
  4. Macethe original

Fit is the average pairing score against mushroom, allspice, ginger. Candidates are from the same food group and used in at least 100 recipes.
