Got leftover red onion from making gravy? Add mushrooms for a great relish in a sausage sandwich. (No picture – it looks gruesome despite being very tasty).
Red onion and mushroom relish:
1 teaspoon sugar
2 red onions, finely sliced
¼ teaspoon baking powder
100ml beef stock
6 chestnut mushrooms, finely sliced
1 sprig thyme, leaves picked
1 teaspoon mustard
1 tablespoon balsamic vinegar
1 teaspoon English mustard
1 tablespoon mushroom ketchup
- Add the sugar to a wide saucepan on a medium heat. Allow to melt then add the onions with a little oil. Stir for a couple of minutes until starting to soften.
- Stir in the baking powder and leave for a couple of minutes to colour. Gradually add the stock a splash at a time to deglaze the pan, then add the mushrooms and thyme.
- When the mushrooms have browned, add the remaining ingredients and allow to bubble together for a couple of minutes. Check for seasoning and serve with something really savoury.
