Red Onion Relish

Red Onion Relish

This easy and delicious recipe is marmalade inspired, soft, sweet caramelised onion relish. Use this recipe to add to so many dishes like hot dogs, homemade burger, roast beef, on breakfast eggs or with cheese. My favourites to use with this relish are a mature cheddar and red onion toastie or with a goats cheese and red onion relish tart.

You can adjust the recipe to make it healthier. Instead of olive oil you can use a coconut oil and instead of brown sugar try honey or maple syrup for vegan option. Furthermore, using butter instead of olive oil is also a delicious (not so healthy) alternative. Make this recipe without vinegar if you like. The sugar alone gives a caramelized flavour to the onions – perfect for burger toppings. Although, if you don’t use vinegar it won’t last so should be eaten immediately (or a day or two!)

This recipe uses red wine vinegar and brown sugar for the soft, sweet, caramelized onion flavours. Will keep for 2 months in the fridge.

I love to add in some chopped Rosemary to this, it complements the relish with a deep herb flavour which works great if you are serving with a joint of meat.
