Method
Using a chef's knife, slice the peeled red onions crosswise into uniform 3mm thick rings.
Tightly pack the sliced onion rings and whole star anise pods into a clean, heatproof glass jar, pressing them down gently to minimize empty space.
Combine the white vinegar, water, granulated sugar, and kosher salt in a medium saucepan. Bring to a rolling boil over medium-high heat until the liquid reaches 100°C/212°F, stirring frequently until the sugar and salt have completely dissolved.
Carefully pour the boiling brine over the onions in the heatproof glass jar, ensuring all the onion rings are completely submerged in the liquid.
Let the jar sit uncovered at room temperature until the brine has completely cooled, which takes about 1 hour. Once cooled, secure the lid and chill in the refrigerator before serving.
Chef's Notes
- Pouring boiling brine over raw onions briefly par-cooks them. This softens their harsh raw sulfurous bite while instantly setting their vibrant pink color and maintaining their structural crunch.
- The star anise provides a subtle, sweet licorice undertone. This bridges the gap between acidic and savory, making these pickles exceptionally well-suited for cured meats and rich liver pates.
- For the most uniform rings, a mandoline slicer is highly recommended. Rings sliced too thin will dissolve into mush, while overly thick slabs take much longer for the vinegar to penetrate.
- To ensure infinite refrigerator shelf life without mold, always keep the onions pressed down so they remain completely submerged beneath the surface of the acidic brine.
Storage
Refrigerator: 6 months — Keeps almost indefinitely due to the acidic brine, but texture and peak flavor are best within 6 months.
