TYPES OF ONIONS
Yellow Onions – They are versatile and have a higher sulphur content than the white onions they yield. They have a stronger, more complex flavour. They contain quercetin, which is used as an ingredient in supplements, beverages and foods.
Sweet onions – are flat and oval rather than round, they are lighter in colour, have a less opaque skin and contain added sugars, making them good for baking and fillings. They are also great for making onion rings.
White onions – White onions are the crunchiest. They have a high water content. Their flavour is milder and sweeter than yellow onions, making them good for eating raw and in salads. White onions have blood thinning properties as they contain high levels of flavonoids and sulphur compounds.
Red onions – Red onions are better eaten raw. They are great for sandwiches and our local delicacy, suya. They can also be used for cooking.
Shallots – They have a smaller shape and are milder. They are crunchy and have a more subtle flavour. Instead of forming a single bulb, they grow in clusters like garlic.
Scallions – Also known as spring onions or green onions, scallions are very young and milder onions that are harvested before the onion has had a chance to develop. Both the long, slender green tops and the small white onion are edible. They can be eaten raw or cooked.
Leeks – Leeks are one of the most versatile onions. They are also great in soups. You can combine them with bacon and also use them as stuffing.
Onions have the rare ability to be sweet, pungent, aromatic and savoury all at the same time. Their sulphur content, while howling, is what gives them their flavour and makes them an ideal addition to various types of recipes.
Most importantly, they are low in calories. So, the next time you buy your onions, make sure you know which variety you need in each case.
