This recipe is healthier than any other pickled onions recipe and this is why

For this quick-pickled red onions recipe, I use:
- Red onions: Studies showed that they eliminates toxins and are packed with immune boosting nutrients. So I use red onions for this delicious pickled recipe.
- ACV and brown rice vinegar: On the other hand, I have added an organic apple cider vinegar (instead of regular vinegar) and brown rice vinegar. The taste of this combo is deliciously interesting. Apple cider vinegar has a lot of benefits for your body from improving digestion to reducing blood sugar levels. I mix it with brown rice vinegar for its slightly sweet flavor. It is made from fermented rice.
- Coconut sugar: I use it instead of regular sugar that helps you to avoid sugar pikes. It contains potassium and magnesium too. I had white coconut sugar in my pantry but feel free to use brown coconut sugar too. It is the same.
- Mustard seeds and Juniper berries: a fab addition to enhance the flavors and add extra nutrients.
Et voila ! This is a delicious pickled red onions recipe that makes a difference for your body.
