The best part of all it’s quick and easy to make. There’s no muss and no fuss. Just slice up your onions and let it cook for the most part.

If you don’t want them sliced you can also dice up your onions. Dicing them up makes this sweet balsamic onion relish recipe even easier to use as a topping for small bites!

Onions are one of our favorite root vegetables and we go through them often. In our house we eat about one to two onions a day. We love them grilled, sautéed, caramelized or even raw in a salad or sandwich.

    Hi,
    I’m a little confused, do you put the liquid into the jar or do you strain the onions and only put the onions in the jar?
    Thanks 🙏

      We reduce the liquid and it becomes a bit thicker and coats the onions. We always store it in the liquid that’s created when making.:)

FAQs

What is onion relish made of? ›

A wonderfully rich mixture of onions, balsamic vinegar and sugar - perfect with cheese. Suitable for vegetarians.

What to use instead of balsamic vinegar for caramelized onions? ›

You can use butter, oil or a combination of both to caramelise your onions. Butter adds more flavour than oil, but it does have a tendency to burn. A combination of butter with the higher smoke point oil helps with this issue.

Why add vinegar to caramelize onions? ›

Tip: use apple cider vinegar for white and yellow onions and balsamic vinegar for red onions. Tip: the vinegar serves to deglaze the pan, adds acidity, and brings this recipe together by boosting the tangy and savory flavors of the caramelized onions. If the onions stick to the pan, that's fine.

What's the difference between onion relish and chutney? ›

In general, chutneys have a chunky spreadable consistency much like a preserve and are usually made with fruit. On the other hand, relishes are hardly cooked, use little or no sugar, are more crunchy to the bite, and use vegetables.

How long does onion relish last in the fridge? ›

Spoon relish into bowl; cover and refrigerate about 3 hours. Store unused relish in covered container in refrigerator for up to 2 weeks.

Is it better to caramelize onions with butter or oil? ›

You can use either oil or butter to caramelize onions — but ideally, you use a combination of both! I like to use olive oil, and this cooking fat tolerates heat particularly well. Meanwhile, butter adds a distinctly rich flavor to the caramelized onions.

Is caramelized balsamic vinegar the same as balsamic vinegar? ›

Caramelised Balsamics are made by cooking down the balsamic vinegar for a long time. This reduces down the liquid component, thickening the balsamic and drawing out the sugars.

How does Gordon Ramsay caramelized onions? ›

Caramelize the onions: Heat about 1 tablespoon of canola oil in a large skillet or dutch oven over medium-low heat. Once hot, add the onions and stir to coat. Let cook, stirring every 5-10 minutes, until deeply caramelized, about 1 ½ - 2 hours.

What kind of onion is best for caramelizing? ›

You can caramelize any kind of onion, but yellow or Spanish onions tend to offer the most balanced-sweet-savory flavor profile and are the most versatile for different dishes. Sweet onions, such as Vidalia or Walla Walla work too, but keep in mind that their flavor will become even sweeter once caramelized.

Why do you add baking soda to caramelize onions? ›

Baking soda makes the onions more alkaline, which speeds up the browning reactions necessary for properly caramelized onions. But it also weakens the pectin that holds the onion's cells together, turning what should be soft but distinct pieces of browned onion into a nauseating stew of pea-green mush.

Why do you soak chopped onions in water? ›

When preparing raw onions, soak in cold water before hand to remove some of the pungency and soften the flavor. However since soaking too long will dilute the flavor, soaking in cold water for 5 to 10 minutes is recommended.

Do you caramelize onions diced or sliced? ›

Usually caramelized onions start with thinly sliced onions, but you can also work with diced or chopped onions. To caramelize, just place a heavy pan over medium low heat and heat up some butter or olive oil.

Should you cut onions vertically or horizontally? ›

Slicing Onions Lengthwise vs.

If you are cooking the onions, as for caramelizing them, you'll likely want to slice them lengthwise, or from root to stem. That way they will hold their shape better during the cooking. Crosswise cut onions tend to fall apart when cooked. If that's what you want, fine.

What is relish made out of? ›

What Is Relish Made Of? There are three key ingredients in relish: produce (fruits, vegetables or a mixture), vinegar, and sugar. Additional ingredients are often added, including spices like mustard seed to make old-fashioned mustard pickle relish or mayonnaise to make crisp onion relish.

Is relish just diced pickles? ›

In North America, the word "relish" is frequently used to describe a single variety of finely chopped pickled cucumber relish, such as pickle, dill and sweet relishes.

What's the difference between cranberry sauce and relish? ›

There is an important difference between cranberry sauce and cranberry relish and that is that cranberry relish is made from raw ingredients blended in a food processor (it's more fresh and tart tasting) and cranberry sauce is cooked and often much sweeter than relish.

What is onion sauce made of? ›

Many various ingredients may be used in preparations of onion sauce, such as cream, milk, butter, chicken broth, wine, port wine, beer, lemon juice, flour, salt, pepper, cayenne pepper, nutmeg, dry mustard, sage and other herbs, mushroom ketchup, bread crumbs, bacon and others.
