Tudor Cottage B&B's Homemade Brown Sauce (Spiced Plum Ketchup)

Potted Prawns
Potted Prawns

It has to be admitted that this is a labour of love, but it is a very therapeutic way of dealing with a glut of plums on a cold and dreary day; it fills the house with the most amazing Autumnal aroma and the resulting shiny piquant brown sauce will put you off HP for ever.


This makes enough for about 4 x 1 lb jam jars (sterilised, see Helpful Hints)

  • 1 kg plums, halved and stones removed 

  • 300g onions, peeled and roughly chopped 

  • 600ml wine vinegar 

  • 500g light soft brown sugar 

  • 3 tsps. ground cinnamon 

  • 2 tsps. ground coriander 

  • 1 tsp. mustard powder 

  • 3 fat cloves of garlic, chopped 

  • 3 tbsps. maple syrup 

  • Oven 180c, 160 fan 


  • Put the de-stoned plum pieces and the onions into a deep roasting pan. Add half the vinegar and all the other ingredients except the maple syrup.  Give them a stir.

  • Bake uncovered in the oven for 3-4 hours, stirring every hour or so. The plums and onions should be meltingly soft and the juice should have become a sticky syrup 

  • Remove from the oven and allow to cool a little.

  • Transfer the aromatic mixture to a food processor and whizz to a smooth purée. 

  • Transfer to a large saucepan and stir in the remaining vinegar Bring to the boil and simmer, stirring occasionally, until it thickens and becomes a pleasingly thick ketchup consistency; about half an hour. Add the maple syrup, pour into warm sterilised jars and seal.

Helpful Hints

An easy way to sterilise jars is to put them through a hot cycle of the dishwasher.  Keep them in a low oven until you are ready to fill them.

Allow to mature and mellow for at least 2 months before consumption

Sealed jars of brown sauce should keep at least 12 months.
