Ingredients
Method
- Slice the onion to a medium thickness, using a mandolin or a knife and keeping the slices as even as you can.
- In a small pot, add the vinegar, water, garlic, sea salt, sugar, mustard seeds and peppercorns.
- Bring to a rapid boil, then turn off the heat and let cool for 5 minutes.
- Meanwhile, pack the onion slices and thyme sprigs into a glass jar.
- Pour the slightly cooled liquid over the onions, making sure they are all covered.
- Refrigerate for 2 to 3 hours. The longer they chill, the more pickled they get.
Notes
The pickled onions will last in the refrigerator for up to 2 weeks.
