The full ingredients list and instructions are found in the printable recipe card at the end of this post. I highly recommend reading the blog post all the way through so that you don’t miss any tips or substitution suggestions, to ensure that you have all the ingredients and equipment required and understand the steps and timings involved.

One of the great things about these pickled jalapeño and red onions is that you can get them prepped and pickling before you start dinner, and by the food is on the table, you pickles are ready to enjoy too.

With honey, garlic, and of course the spicy jalapeño chilies, this pickled topping is sweet and spicy, and perfect not only for Mexican and Tex-Mex dishes but on top of grilled chicken or steak, in wraps or salads, or anywhere you want a little extra spice!

For a nice twist, try using the pickling liquid in place of plain vinegar in homemade vinaigrettes and marinades.


Ingredients & Equipment Used In This Recipe

While most ingredients can be bought in grocery stores, for your convenience, any specialized or notable ingredients and equipment needed for this recipe have been linked to Amazon or other stores if available online.

It may not include staple ingredients such as oil, salt, sugar, etc., as you’re likely to have those in your kitchen. The complete list of ingredients with measurements is found in the recipe card.

Recipes on The Purple Pumpkin Blog use both cup measurements and/or weighted measurements. American cups and kitchen food scales are handy pieces of equipment to have in your kitchen as it means you’ll be able to make all of the different recipes on my blog. I try to give American, imperial, and metric measurements in my recipes. Please note, you can mix cup measurements with weighted measurements, but never mix imperial (pounds, ounces, pints, etc.,) with metric (kilograms, grams, litres, etc.,).
