Ingredients

  • 1 Large Red Onion (*Note 1)
  • 1/2 Cup Apple Cider Vinegar (*Note 2)
  • 1 Tbsp Granulated Sugar
  • 1 1/2 tsp Salt
  • 1 Cup Hot Water (*Note 3)

Instructions

  • Slice the onion as thin and evenly as possible. I recommend a mandoline to ensure consistency.
  • Add as many red onion slices into a jar as possible. I recommend a sealable glass mason jar (16 oz).
  • Add the vinegar, sugar, salt and warm water to a medium size bowl and stir until the sugar and salt are dissolved.
  • Pour the vinegar mixture over the sliced onions, ensuring the liquid completely covers the onions. Marinate for at least an hour before enjoying to maximize flavor.
  • Store in an airtight container for up to three weeks.

Notes

Note 1: If you own a mandoline, now is the time to break it out. You want the slices thin and as even as possible.
Note 2: You could use Distilled White Vinegar or White Wine Vinegar in place of the Apple Cider vinegar for a stronger, more pronounced flavor.
Note 3: The water doesn't need to be heated, but it needs to be hot from the tap. This ensures it's hot enough to dissolve the sugar and salt.
