Notes

Serving Suggestions

These pickled onions are the ultimate finishing touch for:

Tacos & burritos
Grain bowls & salads
Burgers & sandwiches
Grilled meats & roasted veggies

Storage: Keep in an airtight container in the refrigerator for 2–3 weeks. These onions don’t last as long as vinegar-based pickles, so enjoy them fresh!

Optional: Add 1-2 tbsp water to mellow out the acidity a bit with out losing the crunch.

Flavour Boost: Add some white pepper, traditional pickling spices like whole peppercorns, dill seeds, or mustard seeds for extra depth.

Lime Juice Matters: Preferably always use freshly squeezed lime juice, it makes all the difference! Bottled lime juice contains preservatives that can alter the taste.
