🥗 Ingredients

The Produce

  • 2 large Red Onions (very thinly sliced into half-moons)
  • 2 cloves Garlic (peeled and smashed)
  • 1 inch Fresh Ginger (sliced into thin coins)

The Brine

  • 1 cup Apple Cider Vinegar (high quality with 'the mother' if possible)
  • 1/2 cup White Distilled Vinegar (for sharp acidity)
  • 1/2 cup Water (filtered)
  • 3 tablespoons Pure Maple Syrup (or granulated sugar)
  • 1.5 teaspoons Sea Salt (fine grain)

Aromatics & Spices

  • 1 teaspoon Black Peppercorns (whole)
  • 1/2 teaspoon Red Pepper Flakes (for a subtle heat)
  • 1/2 teaspoon Coriander Seeds (whole)
  • 1 piece Dried Hibiscus Petal (optional, for an intense pink color)
  • 1 Bay Leaf (dried)

👨‍🍳 Instructions

  1. 1

    Thoroughly wash a 32-ounce (1 quart) wide-mouth glass Mason jar with hot soapy water and dry it completely.

  2. 2

    Peel the red onions and slice them in half from pole to pole. Slice them as thinly as possible (about 1/8 inch) using a sharp chef's knife or a mandoline for uniform thickness.

  3. 3

    Place the sliced onions into a large heat-proof bowl. Pour enough boiling water over them to submerge; let sit for 20 seconds, then drain immediately. This 'blanching' step removes the harsh raw bite.

  4. 4

    Pack the drained onions into the clean glass jar. Tightly pack them but leave about an inch of headspace at the top.

  5. 5

    Nestle the smashed garlic cloves, ginger coins, bay leaf, and the dried hibiscus petal (if using) into the sides of the jar amongst the onions.

  6. 6

    In a small non-reactive saucepan, combine the apple cider vinegar, white vinegar, water, maple syrup, sea salt, peppercorns, coriander seeds, and red pepper flakes.

  7. 7

    Place the saucepan over medium-high heat and bring the mixture to a gentle simmer, stirring occasionally to ensure the salt and syrup are fully dissolved.

  8. 8

    Once simmering, remove the brine from the heat. Let it sit for 2 minutes to allow the spices to begin steeping.

  9. 9

    Carefully pour the hot brine over the onions in the jar, ensuring they are completely submerged. Use a clean spoon to press down on the onions to release any trapped air bubbles.

  10. 10

    Let the jar sit uncovered at room temperature for about 30 to 45 minutes until the liquid has cooled down significantly.

  11. 11

    Once cool, seal the jar with a non-reactive lid (plastic lids are best for vinegar) and give it a gentle shake.

  12. 12

    Place the jar in the refrigerator. While they can be eaten after 1 hour, the flavor and color are best after 24 hours of chilling.

💡 Chef's Tips

For the most uniform slices, use a mandoline, but always use the hand guard to prevent injury. If you prefer a softer texture, leave the onions in the boiling water blanch for 60 seconds instead of 20. Avoid using metal lids for long-term storage as the vinegar can corrode the metal; use plastic or place parchment paper between the jar and the metal lid. You can substitute the maple syrup with honey or agave, but avoid artificial sweeteners which can leave a bitter aftertaste in pickles. These pickles will keep beautifully in the refrigerator for up to 3 weeks.

🍽️ Serving Suggestions

Top your favorite street-style carnitas tacos for a bright, acidic contrast to the rich pork. Fold them into a warm grain bowl with quinoa, roasted sweet potatoes, and a tahini dressing. Layer them onto a smoked salmon bagel with cream cheese, capers, and fresh dill. Finely chop them and stir into a potato salad or deviled egg filling for an unexpected crunch. Serve alongside a grilled ribeye steak to help cut through the marbling of the meat.
