  What is Yellow Onion
  Yellow onion is a dry onion that has a strong flavour. Appearance-wise, yellow onions can take a range of colours varying from greenish-white and light yellow to white. The layers of papery yellow onion skin can take either a yellow-brown or a pale golden shade. Compared to white onions, yellow onions are richer in their sulphur content. This is the main reason for their relatively complex and stronger flavour profile.
  Yellow onions are rich in minerals, dietary fibre, vitamins, and antioxidant compounds, which make them a simple way of boosting the nutritional value of your daily diet. They are frequently consumed raw, roasted, grilled, or sautéed as they give your taste buds a sweet and mild taste.
  Yellow onions are an annual crop available between spring and fall. Yellow onion is the most commonly grown onion in northern Europe and in the United States. Farmers then store the cultivated onions for the rest of the year, usually at cool a room temperature in a dark place. If you want to preserve them for an even longer period of time, it is better to wrap them in paper and place in a refrigerator. If the onions are already cut or peeled, it is essential to zeal them inside plastic bags before placing them in the refrigerator so that you will be able to preserve them for a few more days.
  What is White Onion
  White onion is a variety of dry onions with a light flavour profile. Similar to red onions, they have a high sugar and low sulphur content. This leads them to have a relatively short shelf life. White onions are specially blended into a variety of dishes: Mexican and European cuisine, especially because of their mild nature. They always add a fresh and a sour taste to dishes.
  Due to its palatable flavour profile, white onion is used as a central ingredient in making salads, stews and coleslaws. Their low astringency helps them to easily adopt a largely sweet flavour in the dish.
