Sweet and sour onion with tomato is a widely used condiment in Sicily that excellently accompanies dishes of fish or meat, fried or roasted.

In my homeland, speaking of sweet and sour onion, I think the pairing that commonly comes to mind is with fish, such as with fried tuna, or sweet and sour mahi-mahi, although in the latter case it’s not customary to add tomato to the onion.

Or sprinkled over roasted or fried veal liver.

A delicious preparation, also great as a condiment for a rich sandwich, which requires little time and few ingredients to prepare.

Additionally, by taking the time to slowly cook the onion, gently stewing it in the pan, the result will be tasty, yet not heavy.

Contrary to what one might believe, sweet and sour onion has a flavor that is also appreciated by those who do not usually like strong flavors.

It accompanies dishes without overpowering them, but as a worthy condiment, helping to bring out their flavor and tenderness.

Ingredients

2 large onions (dry)
4 ripe tomatoes
2 tablespoons tomato puree
as needed extra virgin olive oil
as needed black pepper (preferably freshly ground)
as needed salt
1 tablespoon sugar
2 tablespoons vinegar (red wine)

Tools

1 Mandoline slicer
1 Pan non-stick
1 Wooden spoon

Steps

For preparing the sweet and sour onion with tomato, finely slice the onions with the mandoline slicer.
Wash the ripe tomatoes and remove the skin and seeds. Chop into pieces.
Sauté the onions for a few minutes over high heat with extra virgin olive oil. Season with salt and pepper.
Then, over low heat, stew with a lid for about ten minutes.
After this time, add the tomatoes to the pan.
Also add 2 tablespoons of sauce.
Stir and continue cooking, adding very little water if needed, until the onion is cooked and the tomato has softened, taking on a cooked aroma.
It will take about another 10 minutes.
When ready, add 1 heaping tablespoon of sugar and two tablespoons of red wine vinegar and stir, leaving on the heat for a few more minutes.
Turn off as soon as the onion no longer emits that intense vinegar smell, but rather a more mature and aromatic scent.
Sweet and sour onion with tomato is now ready. Serve at room temperature.
