Why are onions so incredibly common?
Onions are probably one of the most common crops because they are easy to grow. They don’t require a lot of water to grow and don’t have many pests. They can also be easily grown in home gardens.
Due to their good cultivation, storage, and transport properties, onions are widely and cheaply available worldwide. Onions can be successfully stored throughout the year, in a dry, cool place, and can also be transported well.
Why do onions make food taste better?
Onions typically have a pungent taste, but they are also sweet due to their sugar content.
The taste and smell of onions come largely from the sulfur compounds that are released during slicing or chewing. The sulfur content depends on the type of onion and the quality of the soil. The more sulfur an onion contains, the stronger its taste and smell.
Raw, crispy onions are a common ingredient in salads. Raw onions are an excellent side dish for grilled meats. By cooking, the pungency of the onion ceases, and the taste becomes sweeter as the sugar caramelizes. With longer cooking, the onion will soften and thereby thicken and give bulk to the dish.
