Step-by-Step Guide to Canning Pickled Red Onions
1. Prepare Your Jars
Before you dive into pickling, ensure your jars are clean and sterilized. Submerge them in boiling water for at least 10 minutes, then let them cool on a clean towel. This step is crucial for preventing any bacteria from ruining your delicious creation.
2. Slice and Soak
Thinly slice your red onions using a sharp knife or mandoline for uniform pieces. If you prefer a milder onion flavor, soak the slices in cold water for about 30 minutes, then drain. This step will soften their sharpness, making them even more delectable.
3. Create the Pickling Brine
In a medium saucepan, combine the white vinegar, apple cider vinegar, water, sugar, salt, and any spices you’re using. Bring this mixture to a simmer over medium heat, stirring until the sugar and salt dissolve. Allow it to bubble gently for about 5 minutes, letting those aromatic flavors marry together beautifully.
4. Pack the Jars
Using a funnel, pack the onion slices into your sterilized jars, leaving about half an inch of headspace at the top. If you’ve chosen to add garlic cloves or additional spices, distribute them evenly among the jars.
5. Pour the Brine
Carefully ladle the hot pickling brine over the onions, making sure to cover them completely. Tap the jars gently to remove air bubbles, and add more brine if needed to maintain the proper headspace.
6. Seal and Process
Wipe the rims of the jars with a clean cloth to ensure a good seal. Place the canning lids on top, followed by the rings, tightening them until they’re fingertip-tight (not overly tight!). Place the jars in the boiling water bath, making sure they are submerged by at least an inch of water.
7. Water Bath Processing
Process the jars in the water bath for 10-15 minutes (depending on your altitude), then turn off the heat and let them sit for an additional 5 minutes before removing. Allow the jars to cool completely on a clean towel or cooling rack.
Let the Flavors Develop
Once cooled, check the seals by pressing the center of each lid; it shouldn’t pop back. If sealed properly, your pickled red onions can be stored in a cool, dark place for up to a year. For the best flavor, allow them to marinate for at least a week before indulging, as this time lets the flavors meld beautifully!
