Quick Pickled Red Onions

Pro tips

• Slice onions uniformly thin for even pickling and consistent texture throughout.
• Use freshly boiled water to help the pickling liquid dissolve salt and sugar completely.
• Taste after 30 minutes; they're ready to eat immediately but develop better flavor after 2–4 hours.
• Don't discard the pickling liquid—use it to pickle more onions or add to vinaigrettes.

Substitutions

• White vinegar → apple cider vinegar (more mellow, slightly fruity note)
• Fresh dill → fresh thyme or oregano (different herb profile)
• Granulated sugar → honey (adds subtle floral sweetness)
