1 can sweetened condensed milk
200ml white wine vinegar
200ml white sugar
50g -100g Colemans Hot English Mustard (I prefer milder mustard so I use 50g, a small tin)
Optional 100ml or more of prepared grain mustard
Optional: 200ml good quality mayonnaise e.g. Hellmans (for a creamier sauce)
Combine all the above ingredients. Stir well. Leave to stand for 30 minutes so that all the sugar can dissolve. Give it a good stir to ensure that all the ingredients are well mixed.
Pour into sterilised jars. Refrigerate to set. Serve at room temperature.
Shelf life 4-6 weeks.
Serve with pickled, smoked or cured meats.
Dilute mustard with olive oil and pour over blanched green beans or serve with Cos or Gem lettuce, topped with a few shavings of Parmesan cheese.
