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 kind of onion is best for caramelized onions? ›

The Type of Onion

At least that is what I think. 😄 They aren't as one-noted in sweetness as other onions because they have a touch of bitterness that creates a depth of flavor. But really you can caramelize any type of onion and have a fantastic result. Shallots, white, yellow, sweet, or even red will all do the trick.

What is onion relish made of? ›

Byler's Relish House Onion Relish is made from sweet onions along with fresh peppers, vinegar, and an assortment of spices. Onion Relish can be used as a relish on hamburgers or hot dogs or as a marinade for chicken or other meats.

Why add vinegar to caramelize onions? ›

I usually stick with balsamic vinegar because the flavor complements the onions perfectly. Not only will deglazing pull up tasty sticky bits, it will add even more flavor to your caramelized onions. Continue stirring the onions until they have reached the color you like.

How long does onion jam last in the fridge? ›

How to Store Homemade Onion Jam. Once the onion jam is cooked, transfer to a glass jar or plastic container, and store in the refrigerator. The onion jam will keep refrigerated for up to two weeks, or in the freezer in ice cube trays.

Do onions caramelize better with butter or oil? ›

Our Test Kitchen likes to use butter when caramelizing onions, as it offers the richest flavor. If you avoid dairy or don't have butter, you can caramelize onions in other fat such as margarine or olive oil. Add the onion slices. It's okay if they overlap a bit here because they'll shrink as they cook down.

Why 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.

Is onion chutney the same as onion relish? ›

Relish is a flavouring, usually sweet and sour, which consists of finely chopped vegetables or fruit, vinegar and sugar. Whereas chutney is more sweet and fruity, relish usually contains cucumber, courgette, tomato, rhubarb or onion, and the pieces of fruit or vegetables are somewhat coarser and crunchier.

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.

What is Plummer's relish? ›

Plummer's Relish appears to be a take on Branston Pickle, a popular condiment in Britain, dating back to the 1920's. Branston Pickle is used in sandwiches, as DCI Barnaby references, and is most commonly associated with the so-called "ploughman's lunch", a meal of bread, cheese, pickle and often ham.

What is the secret to caramelize onions? ›

As soon as the onions start sticking to the pan, let them stick a little and brown, but then stir them before they burn. The trick is to leave them alone enough to brown (if you stir them too often, they won't brown), but not so long so that they burn.

Do you caramelize onions covered or uncovered? ›

The winner was a technique heralded by America's Test Kitchen, which begins by steaming the onions, covered, over high heat. The onions are then cooked uncovered over medium-high heat until caramelized, at which point a baking soda solution is stirred in.

Should you add sugar when caramelizing onions? ›

No! Onions already contain natural sugars, which is why they're so perfect for caramelizing. This process brings out those sugars to make them more prominent. Adding more sugar would make them too sweet and mess with the flavor.

Are white onions Vidalia? ›

Sweet onions, like Maui and Vidalia, are technically white onions - but they have a much higher sugar content, and a lower sulphur content, so they don't have that sharp bite to them.

Is homemade jam good after 5 years? ›

Shelf Life of Homemade Jam

What is the trick to caramelizing onions quickly? ›

Once the water is boiling or close to it, put a lid on the pan so the onions can steam. This essentially massively speeds up the process of wilting the onions, which can be the first 15-20 minutes of the sautéing process.

Are red or white onions better for caramelizing? ›

What Kind of Onions Are Best for Caramelizing. You can use any onions for caramelizing, red, yellow, white, sweet varieties all work. If you are using sweet onions, like Vidalia, which are already sweeter than your basic yellow or red onions, then you can skip the optional sugar.

Which onion has the most flavor when cooked? ›
