Mushroom Catsup
Ingredients
Directions
Macerate
Macerate the mushrooms with salt for three to four days.
Strain the liquid.
Measure the liquid.
Reduce and season
Boil the liquid quickly until reduced by half.
For each quart of liquid, add ½ oz black pepper or ¼ teaspoon cayenne and 1 drachm mace.
Settle and bottle
Pour the catsup into a clean jug or jar.
Cover with a folded cloth.
Keep in a cool place overnight.
Gently pour off the sediment.
Bottle the catsup, corking well.
Optionally, add 1 teaspoon of salad oil to each bottle before corking to exclude air.

What each ingredient does
- Mushrooms
- Provide the main flavour and liquid that becomes the ketchup after maceration.
- Salt
- Draws juice out of the mushrooms and preserves the liquid against spoilage.
- Black peppercorns
- Add sharp, pungent heat that seasons the reduced liquid.
- Mace
- Adds warm, aromatic spice to the finished ketchup.
The step that matters
Boil the liquid quickly until reduced by half. Rapid boiling concentrates the flavour and thickens the liquid while driving off water, which helps the ketchup keep. Slow boiling can leave it weak and more prone to spoiling.
