Moreover, they are very economical: low cost, high yield as someone would say.
Made with Borettane onions, a variety of onions well-known for their deliciousness, with a classic flat shape.
Generally, the fundamental ingredients of sweet and sour are vinegar and sugar or honey, to which some aroma can be added if desired.
In my case, since the onions were very tasty and fragrant, I did not add any aromas. The preparation is really quick and the result is guaranteed.
Sweet and sour pearl onions cook in a mixture of water, sugar, and vinegar and caramelize at the end of cooking until they take on the classic golden color. To enjoy them at their fullest flavor, let them cool slightly.

They are very practical but be careful: store them in the fridge in the closed package for no more than 2/3 days; after that, they tend to mold.
