Fermented onions have a wonderful mellow pickled onion flavour that is great with a plate full of vareniki or in a cheese sandwich. They are perfect for parties, sliced up in salads or eaten in tacos.

Fermenting onions is a great option for anyone who finds raw onion to be too strong. The mild flavour is easy to digest, and they will last for at least a month in the fridge. They are a great replacement for any recipe calling for raw onions.

Ingredients

12 small cocktail onions or 2 large onions sliced
1 1/2 tbsp non-iodized salt
2 cups filtered water
1 tbsp culture (optional – see notes)

Instructions

Cut the ends off the onions and peel them.
Place the onions in a glass jar for fermenting.
Dissolve the salt into the water to make a brine. Mix in the culture – if you are using one.
Pour the brine over the onions. The onions will float, so use a weight to keep them submerged below the brine.
Leave the onions somewhere cool and dark to ferment. Ferment for 1 week.
After fermenting, store in the fridge and use within 1-2 months.

Notes

I always recommend being very clean for all your ferments, especially if you are fermenting for more that just a few days or are not using a starter culture.
I usually use a mason jar with a glass weight but it does have a risk of contamination from free range molds, yeasts and bacteria. If you are making a large amount, then I recommend using a fido jar (affiliate link.)
Onions don’t need a starter culture. However, if you want to add some culture, then I recommend using either sauerkraut juice or a commercial vegetable culture.
