Old English Recipe for Mushroom Catsup
Ingredients
Directions
Salt the mushrooms
Lay two quarts mushrooms and one-quarter pound salt in an earthenware pan in alternating layers of mushrooms and salt.
Let them lay six hours then break into bits.
Set in a cool place for three days, stirring thoroughly every morning.
Spice and cook
Measure the juice when you have strained it and to every quart allow half an ounce of allspice, the same quantity of ginger, half a teaspoon of powdered mace, and a teaspoon of cayenne.
Put into a stone jar and cover closely.
Set in a saucepan of boiling water over the fire and boil five hours hard.
Take it off and empty into a porcelain kettle and boil slowly half an hour longer.
Settle and bottle
Let it stand all night in a cool place until settled and clear.
Pour off carefully from the sediment and bottle, filling the bottle to the mouth.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Main body of the ketchup, releasing juice that becomes the sauce base.
- Salt
- Draws moisture out of the mushrooms and helps preserve the liquid.
- Vinegar
- Adds acidity that sharpens flavour and helps preserve the ketchup.
- Allspice
- Contributes warm, aromatic spice flavour to the sauce.
- Ginger
- Adds aromatic, gently pungent flavour to the sauce.
The step that matters
Boiling the strained juice for five hours. Long, hard boiling reduces the liquid and concentrates flavour while driving off water, so the ketchup thickens and keeps. Too little boiling leaves it thin and more likely to spoil.
Swap the mace
How well each one fits the dish's main ingredients (mushroom, tomato, ginger, vinegar, allspice, sugar):
- Cinnamonfits better
- Clovefits better
- Thymefits better
- Macethe original
Fit is the average pairing score against mushroom, tomato, ginger, vinegar, allspice, sugar. Candidates are from the same food group and used in at least 100 recipes.
