Sticky red onion relish (slimming world friendly)

I love a relish or sauce on the slimming world plan, You can take a plain grilled piece of fish or chicken or a steak and liven it up with some but they are usually mega high in sugar and so mega high in syns. This one is sugar free and syn free yay!!

Sticky red onion relish

500g red onions (thinly sliced)
100ml balsamic vinegar
150ml cider vineger
2 tbsp powdered sweetener
1 clove garlic (crushed)
1 tsp salt and 1 tsp pepper

Thinly slice the red onions and place in a large heavy based saucepan. Add the vinegars, garlic and splenda then simmer for approximately one hour on a very low heat until it has reduced and made a thick sticky relish. Season to taste with salt and pepper .

Keeps well in the fridge for a couple of weeks (can also be kept for longer if kept in sterilised jam jars) .


  1. Looking forward to this with SW free pate and HE bread roll :) delish!

  2. Oh my. I am making this!

    Will take some to my groups taster too :) they are in for a treat

  3. Do you need to simmer this with the lid on or off? I've tried making this before but left the lid on and even after more than an hour it was still watery :(

  4. Lid off , this allows the liquid to evaporate : )

  5. Have made this recipe several times. It's delicious. Thanks you for sharing it ��

  6. My pleasure Alison glad you enjoyed Xx

  7. Can you serve this with curry
