How to make this easy recipe?
Pickling red onions could not be any easier. It’s literally just these five easy steps steps, cut onions, put them in a jar, pour over the liquid, shake and wait!
Traditionally, white sugar is used to make the pickling juice. We are trying to use less white processed sugar so I opted for coconut sugar instead for this recipe. It’s doesn’t affect the taste of the onions, but it does tint the pickling juice slightly. If you prefer you could always use regular white sugar instead of the coconut sugar.
