Recipe Ingredients
For these pickled red onions you'll only need 3 Ingredients.
Red Onion - slice your red onion as finely as possible. If you have a mandolin this would be a good way to slice them, however I do not trust myself within an inch of a mandolin so opted to hand slice them.
White Wine Vinegar - you'll need 150 mls or ⅔ of a cup of good quality white wine vinegar.
Sugar - 1 tablespoon of white sugar.
Water - 100mls or 3.3 fluid ounces of water.
And that's it! This is why they are so simple!

- Heat the white wine vinegar, water and sugar in a small saucepan over low heat until simmering. Simmer for 3-4 minutes until the sugar has dissolved.
- Turn off the heat.
- Add in the onion and stir.
- Sit for 1 hour
- Transfer to a large jar.
It's that simple!

How do I cut onions for pickles
The key to these onions is to finely slice the onions. You can use a sharp kitchen knife, or a mandolin. Try and keep the slices consistent so that they pickle evenly.
Can I substitute any ingredients?
I haven't tried any substitutes in this recipe, however the only substitute I would consider is swapping the white wine vinegar for plain white vinegar, or apple cider vinegar.
There are many other onions you can pickle - whole onions for example, but I would not substitute red onions for brown or white onions.
How do I store these onions?
Store your pickled red onions in a large mason jar or any jar that can seal properly. I use a 350ml jar that easily fits one whole sliced onion plus the liquid.
These will last in the fridge for up to 2 weeks in a clean, sealed jar.
