Walnut Catsup

Ingredients

Directions

Prepare the walnuts

  1. Prick the walnuts with a pin and layer them in an unglazed jar with a light sprinkling of salt.

  2. Pound the walnuts lightly with a piece of wood to bruise them.

  3. Let the mixture stand for ten days, stirring daily.

Make the ketchup

  1. Strain the juice into a saucepan.

  2. Cover the walnut shells with boiling vinegar, crush to a pulp, and strain through a colander into the saucepan.

  3. Add spices: 1 ounce each of black pepper and ginger, ½ ounce each of cloves and nutmeg, a pinch of cayenne, a bag of celery seed, and 1 minced onion for every 2 quarts.

  4. Boil the mixture for one hour for each gallon.

Bottle and seal

  1. Bottle the catsup when cold, dividing the spices equally among the bottles.

  2. Cork and seal the bottles.

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

What each ingredient does

Young tender walnuts
Provide the main body and flavour of the ketchup as they break down over the long steeping.
Boiling vinegar
Extracts flavour from the walnut shells and adds sharp acidity that helps preserve the ketchup.
Coarse sea salt
Draws juice out of the walnuts and helps preserve the mixture during the ten-day standing.

The step that matters

Boil the mixture for one hour for each gallon. Boiling concentrates the flavour and helps reduce the risk of spoilage, so the time should match the batch size rather than be cut short.

Swap the onion

How well each one fits the dish's main ingredients (walnut, vinegar, pepper, ginger, clove, nutmeg, celery):
