Mexican Quick Pickled Onions Recipe for Tangy Pink Onions to Brighten Your Tacos

What we love about this Mexican quick pickled onions recipe is that it’s super easy to make, it’s really very versatile, and you can eat these Mexican-style pickles in no time. While you could spoon these pink pickles onto tacos in half an hour, if you leave them for a few hours, the sliced onions or shallots would have started to soften and the flavours will have begun to meld together.

Leave these quick pickles overnight and they’re even more zingy, but I have to say that I love them best after 2-3 weeks when they’re not only more tangy, but they’ve softened and are a better companion to heavier Mexican dishes, and dare I say it, Tex-Mex dishes, such as a big old bowl of chilli con carne.

Tips to Making These Mexican Quick Pickled Onions

Just a few tips to making these quick pickled onions. As these are quick pickles – also called refrigerator pickles – they don’t last long, as in they don’t last the many months that pickles that have gone through a bathing/canning process do.

Some pickle experts recommend that this style of quick pickles be used in a few days, however, we live in a country where pickling is a key element of the culinary culture and people are pickling every day and they’re not paying attention to how long pickles are sitting in their kitchen. They don’t refrigerate their pickles, not even quick pickles.

The advice of health authorities regarding the longevity of refrigerator quick pickles tends to be to keep them anything from a few days to a few weeks as long as they’re kept in a sterilised jar in a refrigerator.

But I’ve kept these Mexican quick pickled onions in the fridge for three weeks and they’ve still tasted absolutely wonderful and we haven’t been sick. But you need to use your best judgement.

We make and keep these pickles in small jars, as I suggest in this recipe, so after we open them we finish them within a few days. I do not recommend making these pickles in a larger jar that you’ll be digging in and out of over a period of weeks. We like these vintage mason jars and clip-top Kilner jars, but we also save jars for recycling, which we use for pickling, sterilising them before we pickle.

When it comes to vinegar, we recommend a cider vinegar or distilled white vinegar, or a combination of the two. For your salt, we suggest sea salt or Kosher salt. We don’t recommend fine grained table salt or iodised salt as this generally contains potassium iodide, dextrose and chemicals such as calcium silicate, sodium silicoaluminate, etc.

If you’re not sure what kind of salt you have, stir a little in a glass of water. If the water is a bit cloudy, it’s table salt, and it will muddy your pickling liquid, while the potassium iodide can cause the pickles to darken in colour.
