- 1.5 cups Apple cider vinegar
- 0.5 cup Water
- 2 tablespoons Erythritol
- 1 teaspoon Salt
- 1 teaspoon Whole black peppercorns
- 2 cloves Garlic cloves
- 1 leaf Bay leaf
Directions
Step 1
Peel and thinly slice the red onion. Set aside.
Step 2
In a medium saucepan, bring the apple cider vinegar and water to a gentle simmer over medium heat. This should take about 3-4 minutes.
Step 3
Once simmering, reduce the heat to low and stir in the erythritol and salt until fully dissolved.
Step 4
Add the whole black peppercorns, garlic cloves (lightly crushed with the back of a knife), and the bay leaf to the simmering mixture.
Step 5
Remove the saucepan from heat and let it cool for about 2 minutes.
Step 6
Place the sliced onions into a clean, heatproof jar or container with a lid.
Step 7
Pour the hot vinegar mixture over the onions, ensuring they are fully submerged.
Step 8
Let the jar sit at room temperature to cool down for approximately 20-30 minutes before sealing tightly.
Step 9
Refrigerate for at least 1 hour before serving. For best flavor, allow the onions to pickle for a full day.
Step 10
Store in the refrigerator for up to 2 weeks.
