HOW DO YOU MAKE PICKLED RED ONIONS?

Finely slice red onions, either by hand or with a mandolin if you have one.

Place onion slices into a sterilized mason jar with a lid.

In a heatproof measuring jug, pour apple cider vinegar and boiling water.

Stir in sugar and salt until dissolved.

Pour vinegar mixture into jar to cover sliced red onions.

Put on lid and thoroughly shake the jar then allow to settle.

Ensure the onions are submerged under the liquid- if they are not, push them down with a spoon. Seal jar with lid.

Place onion jar in the fridge and allow to marinate for at least 30 minutes before using.

Pickled onions will last 2-3 weeks in the fridge.

TIPS AND TRICKS FOR MAKING THIS QUICK PICKLED ONIONS RECIPE 

• The most important part of making quick pickled red onions is to cut the red onion very thinly. This helps them to absorb the vinegar and pickle them with that tangy flavor. I use a mandoline or you can use a very sharp knife to do this as well. 
• You can substitute the sugar with honey or maple syrup if you want to use natural sugar instead of white sugar. 
• If you are wondering if you can – can this recipe the answer is no. This is a quick pickling refrigerator recipe not a canning recipe. You will not want to use this as a canning recipe and put it in a water bath. With canning you want to always follow a recipe designed for canning to avoid botulism.
• If you keep this in the fridge for up to the two weeks you will want to make sure the onions are submerged under the liquid as best as you can to keep them fresh and so they don’t dry out. 
• For a hint of spice add red pepper flakes to the red onions.
