How to Make Pickled Red Onion
Prepare Your Onions: Start by peeling and thinly slicing your red onions; aim for even slices to ensure consistent pickling throughout. A mandoline works wonders here if you have one.
Make the Brine: In a saucepan over medium heat, combine white vinegar, sugar, salt, and water until sugar dissolves completely while the mixture becomes aromatic.
Pack Your Jars: Place sliced onions in clean jars tightly but without crushing them; this ensures every slice gets covered in that tangy brine.
Pour in the Brine: Carefully pour your warm brine over the onions until fully submerged; leave some space at the top for expansion as they cool.
Seal & Cool: Tightly seal the jars with lids; let them cool at room temperature before transferring them to the fridge where they’ll develop their flavors.
Taste Test: After at least an hour in the fridge (or overnight if you can wait), grab a fork and enjoy! Adjust seasoning as needed for next time or add spices like peppercorns or bay leaves for extra flair.
Now you’ve got delicious Pickled Red Onions ready to jazz up any meal! Enjoy experimenting with this versatile condiment that’s sure to become a staple in your kitchen.
