Chippy Sauce
First you make something called an HP Brown Sauce:
Ingredients
Apples - 1.8 kg (4 lb), peeled, cored and sliced
Prunes - 450g (1 lb) stoned and sliced
Onions - 2 large, peeled and diced
Malt vinegar - 1.7 litres (3 pints)
Ground ginger - 2 tsp
Grated nutmeg - 1 tsp
Ground allspice - 1 tsp
Cayenne pepper - 1 tsp
Salt - 8 tbsp
Sugar - 900g (2 lb)
Preparation:
Put the fruit and onions into a large pan and cover with water.
Cook until tender. Liquidise or sieve into a large saucepan.
Add the malt vinegar, ginger, nutmeg, allspice, cayenne pepper, salt, and sugar. Cook on a low heat until reduced and thick.
To make “chippie” sauce - add about a third of the total volume of white vinegar. (after cooking - add to existing stock)
This sauce can be filled into sterilised jars or kept in fridge indefinitely.
