Cooking and Preparation Instructions
Step 1: Caramelize the Onions
Kick things off by thinly slicing your onions. Then, heat the olive oil over medium heat in a large pan and toss in the onions. Stir them regularly to ensure they don’t burn. Once they turn golden and emit a sweet aroma, you know your onions are perfectly caramelized.
Step 2: Prepare the Tomatoes
While the onions are caramelizing, start preparing your tomatoes. Lightly score the bottoms, drop them in boiling water for a quick minute, and then transfer them to an ice bath. This technique makes it easy to peel off their skin. Once peeled, dice your tomatoes.
Step 3: Combine the Onions and Tomatoes
When your onions are ready, add the chopped garlic into the pan and let it cook until its aroma wafts through your kitchen. Next, add the diced tomatoes and stir well to combine everything.
Step 4: Add the Sugar and Vinegar
Now, let’s sweeten things up! Sprinkle in the sugar and drizzle the red wine vinegar into the pan. As you stir these additions in, you’ll notice your mixture starting to look more jam-esque.
Step 5: Simmer the Mixture
Turn the heat down and let the mixture gently simmer for about 20 minutes, or until the tomatoes completely break down, forming a thick, juicy blend with the onions.
Step 6: Add the Seasonings
Sprinkle in your salt, ground black pepper, and Italian herbs. Stir everything once again so the seasonings can enhance all of that lovely caramelized onion and tomato flavor.
Step 7: Cook until Thickened
Continue cooking over low heat until you achieve a jam-like consistency. Add the balsamic glaze, stir well, and cook for a further 2 minutes.
Step 8: Store the Jam
Allow your jam to cool down before transferring it to an airtight jar. It can be refrigerated and will stay fresh for up to two weeks.
Options/Substitutions
Option 1: Use different types of onions
While red and yellow onions are traditional choices for this recipe, you’re more than welcome to experiment with different types such as shallots, white onions, or even a mix of several kinds.
Option 2: Use cherry tomatoes
For a more concentrated sweetness, consider swapping regular tomatoes for their smaller, sweeter cousins, the cherry tomatoes.
Option 3: Substitute honey for sugar
If you’re after a more natural sweetener, honey could be a perfect substitute for sugar. Note that this will give your jam a slightly different, more robust sweetness.
Serving Suggestions
