What is Onion?
Onions (Allium cepa) are versatile and widely used vegetables that belong to the Allium genus, which also includes garlic, shallots, and chives. They come in various shapes, sizes, and colors, including white, yellow, and red varieties.
One of the key components of onions is their sulfur compounds, which are responsible for their pungent aroma and flavor. These compounds are released when onions are chopped or sliced, leading to tears in the eyes of those handling them. Onions have a strong and sharp taste, varying depending on the onion type and how it’s prepared. Raw onions tend to be pungent and sulfurous, causing tearing when chopped due to sulfur compounds like allyl sulfides. When cooked, onions become sweeter as their natural sugars caramelize, resulting in a milder flavor with hints of sweetness and depth.
Onions can be used in various ways in cooking. They serve as a flavorful base for soups, stews, and sauces, adding depth and richness to the dish. Onions can also be caramelized to enhance their sweetness, used raw in salads for a crisp bite, or pickled for a tangy flavor.
Onions also offer several health benefits. They are rich in antioxidants, particularly flavonoids and sulfur compounds, which have been linked to various health benefits, including reduced risk of heart disease, improved immune function, and decreased inflammation. Onions are also a good source of vitamins C and B6, as well as dietary fiber, which promotes digestive health.
What is Coriander?

It is native to regions spanning from southern Europe to southwestern Asia but is now cultivated globally for its culinary and medicinal purposes.

In cooking, coriander can enhance the taste of dishes across various cuisines, including Asian, Mediterranean, and Latin American. Both its seeds and leaves are utilized in cooking, with each imparting a unique flavor profile.
