Pickled Onions

These old-school pickled onions start with an overnight salt brine that draws out moisture and firms up the texture. That salt soak is what gives you onions with real snap instead of soft, soggy ones.

The next day, a quick simmer of white vinegar with mustard seeds and horseradish (or peppercorns, your call) builds a brine with serious kick. Each jar gets a bay leaf and a small hot pepper tucked in for slow-building heat that develops over time.

The scalding-then-cold-water trick at the start makes peeling painless. Once packed and sealed in boiling-hot brine, these keep for months and get better with age.

Serve them alongside a roast beef dinner, chop them into relish, or eat them straight from the jar with sharp cheddar and crusty bread. A proper British pub snack, right at home.

Pro Tips

• Use small pickling onions or pearl onions for the best crunch. Larger onions can be quartered.
• Rinse thoroughly after the salt soak. Skipping this step leaves the pickles too salty.
• Wait at least 2 weeks before opening for the flavors to fully develop.
• Sterilize jars in boiling water before packing to ensure a proper seal.

Variations

• Add whole allspice or mixed pickling spices to the brine for a more complex, warming flavor.
• Use apple cider vinegar instead of white for a mellower, slightly fruity tang.
• Toss in a few cloves of garlic per jar for pickled onions with a garlicky punch.
