Notes
TOP TIPS:
- Slice thin: Use a mandoline or sharp knife for even slices that pickle quickly.
- Submerge fully: Press onions under the liquid to keep colour bright.

- Flavour boost: Add peppercorns, mustard seeds or a bay leaf for variation.
- Balance tweak: Prefer less tang? Use half apple cider vinegar, half white vinegar.
