Step 1: Prepare the Onions
- Peel the red onions and slice them thinly into rings or half-moons. Use a sharp knife or mandoline for even slices.
- Place the onion slices in a heatproof bowl or jar.
Step 2: Make the Pickling Brine
- In a small saucepan, combine the lime juice, vinegar, sugar, salt, and spices.
- Heat the mixture over medium heat, stirring until the sugar and salt are completely dissolved. Bring it just to a simmer; do not boil.
Step 3: Combine and Rest
- Pour the hot brine over the sliced onions, ensuring they are fully submerged. Use a spoon to gently press the onions down if needed.
- Let the mixture cool to room temperature.
Step 4: Refrigerate and Enjoy
- Once cooled, transfer the onions and brine to a clean, airtight jar. Seal tightly and refrigerate for at least 1 hour before serving.
- For best results, allow the onions to marinate overnight for deeper flavor.
Serving Suggestions
- Add to tacos, burgers, or sandwiches.
- Toss into salads or grain bowls for a tangy crunch.
- Serve as a condiment with grilled meats or fish.
Tips for Succes
- Color Boost: The acidity from the lime juice naturally enhances the onions’ pink hue. For extra vibrancy, add a small slice of beet to the jar during pickling.
- Balance Flavor: Adjust sugar and salt to suit your taste preferences.
- Storage: Store in the refrigerator for up to 2 weeks in a sealed container.
