Common Mistakes to Avoid

- Boldly using cold water: Always use hot water when mixing with vinegar, salt, and sugar. Cold water can prevent proper dissolving of these ingredients.
- Boldly overfilling the jar: Make sure not to pack too many onions into your jar. Leave some space to allow the pickling liquid to circulate.
- Boldly storing improperly: Store your Quick Pickled Red Onions in an airtight container in the fridge. This will keep them fresh for longer.

- If you prefer them warm:
