Yellow onion is the one that suits most and varied dishes, including Italian sauces. It has thin, thin layers of white flesh and a robust yellowish-brown shell. It’s astringent – which means it has a strong, almost spicy aroma – but it also has a lot of sugar. When cooked, it loses its astringency, becomes very sweet, and takes on a light brown hue.

The sweet onion – also known as Vidalia – is very similar to the yellow one, but its distinct aroma is dedicated to certain things. The sweet onion has thicker leaves, which makes it perfect for slicing. Its high sugar and low sulfur content are very sweet and have a much less intense and strong aroma than other types of onions.

Red onions have a more subtle flavor and a pleasant color. Crispy and slightly sweet, with a faint bitter taste at the end. It doesn’t have as strong a flavor as yellow onions.

The green onion is cylindrical; it is an immature onion, without a bulb, the green color of the leaves gradually fading into the white of what would become a bulb. It can be consumed without limits, under any kind, even boiled, because it does not lose its properties at all.
