As far as nostalgic pickles go, pickled onions would have to be the pinnacle pickle! These baby white onions are brined and then captured in a herb and malt vinegar solution to make them tangy, sweet and crunchy – perfect as a condiment, or eating straight from the jar!
How to make Grandma’s pickled onions: key tips
Popping a plate on top of the submerged onions is an easy way to keep the onions in the brining solution, so that every part of the onion is targeted. Leave them to soak overnight and then peel them the next day (see notes below the recipe).
After peeling the onions, place them in a new brining solution, with a plate on top to keep them submerged. This time they’ll stay in the solution for 2 days. Brining the onions before pickling them draws moisture from the cells, which will help to keep them crisp when they’re pickled. It also enhances their flavour.
Make sure you rinse the onions twice before adding them to the jars with the vinegar solution and spices. You’ll want to rid them of as much salt as possible so that the pickle doesn’t taste overly salty.
Key ingredients in Grandma’s pickled onions recipe
Baby onions (or pearl onions) are just brown onions that have been harvested before they’ve reached full size. You can buy them at selected supermarkets and grocers, and you can also swap them for baby red onions.
Malt vinegar is made from fermented barley and has a tangy, slightly caramel-like flavour. Its distinctive flavour is favoured for a pickle due to its ability to balance the sweetness of the onions.
Peppercorns, allspice, bay leaves, cloves and red chilli all add flavour to the pickling solution. Peppercorns also contain antibacterial compounds. You can use fresh or dried bay leaves and chilli.
