Step-by-Step Guide on How to Pickle Onions

Preparing the Onions

– Choose firm, fresh onions and peel off their outer layers.
– Slice the onions thinly to your desired thickness (rings or half-moons) using a sharp knife or mandoline slicer.

Preparing the Brine Solution

– In a saucepan, combine equal parts vinegar and water. For every cup of liquid, add 1 tablespoon of salt and sugar.
– Bring the mixture to a boil over medium heat, stirring occasionally until the salt and sugar are fully dissolved.

Sterilizing the Jars

– While the brine solution is heating, sterilize your jars and lids by washing them thoroughly with hot, soapy water.
– Place the jars in a large pot, filled with enough water to submerge the jars completely.
– Bring the water to a rolling boil and let the jars boil for at least 10 minutes.
– Carefully remove the jars and lids from boiling water and allow them to cool on a clean towel.

Packing the Onions into Jars

– Fill the sterilized jars with the sliced onions, leaving about ½ inch of headspace at the top.

Pouring the Brine

– Slowly pour the hot brine solution into each jar, ensuring that the onions are fully submerged.
– Leave about ½ inch of headspace at the top to allow for expansion during the pickling process.
– Remove any air bubbles by gently tapping the jars or using a skewer.

Sealing and Storing the Jars

– Wipe the rim of each jar with a clean, damp cloth to remove any spills or residues.
– Place the sterilized lids on top and screw them tightly onto the jars.
– Allow the jars to cool before storing them in a cool, dark place for at least 24 hours to allow the pickling process to take place.

Important Tips for Pickling Onions

1. Opt for firm onions, as softer onions might become mushy during the brining process.
2. Use glass jars instead of plastic containers, as they provide a better seal and prevent any unwanted odors or flavors.
3. Experiment with different seasonings and spices to customize the flavor profile of your pickled onions.
4. Let the pickled onions sit for at least 24 hours before consuming them to achieve the best flavor.
5. Store the pickled onions in the refrigerator once opened to extend their shelf life.
