Sweet pickled onions


I had no idea how easy it was to make these! I always love them on tacos or on top of noodle dishes. Save a jam jar if you can as it’s the perfect size for 1 smallish onion’s worth. You could absolutely add some jazzy spices as well like onion seeds or fennel.


1 smallish red onion

100ml hot water

2 tbsps sugar

1 tsp salt

50ml cider vinegar


Mix everything into the hot water and leave to dissolve. 

Slice the onion as thinly as possible in half moons and stick in the jam jar. 

Pour over the pickling liquid until everything is covered. 

Leave in the fridge overnight before eating. Should keep for at least a week. 

After a few hours they will be soft and the liquid will be a hot pink colour. Amazing.
