Yellow Onions
Yellow onions are the workhorse of the onion family. They have a high sulfur content, which gives them their strong, pungent flavor. This makes them ideal for cooking, as the flavor mellows and sweetens when cooked. Yellow onions are often used in soups, stews, and sauces, as they provide a rich, savory base. They are also excellent for caramelizing, as their natural sugars develop a deep, sweet flavor when cooked slowly over low heat.
When selecting yellow onions, look for firm, heavy bulbs with dry, papery skin. Avoid onions with soft spots or sprouting, as these are signs of age. Store yellow onions in a cool, dry place with good air circulation, away from potatoes, which can cause them to spoil more quickly.
Red Onions
Red onions are known for their striking color and mild flavor. They have a slightly sweet taste, with a crisp texture that makes them perfect for raw applications. Red onions are often used in salads, sandwiches, and salsas, where their vibrant color adds visual appeal.
While red onions can be cooked, they tend to lose their color and flavor when exposed to heat. If you do cook them, try grilling or roasting to preserve some of their natural sweetness. When selecting red onions, choose firm, heavy bulbs with smooth skin and no signs of sprouting.
White Onions
White onions have a sharper, more pungent flavor than yellow or red onions. They are commonly used in Mexican cuisine, where their crisp texture and bold flavor complement the spicy and tangy flavors of the dishes. White onions are also used in soups, stews, and pickling.

Sweet Onions
Sweet onions, such as Vidalia, Walla Walla, and Maui onions, have a higher sugar content and lower sulfur content than other onions, giving them a milder, sweeter flavor. This makes them ideal for raw applications, such as salads and sandwiches, where their sweet taste can shine.

Shallots
Shallots are smaller and milder than regular onions, with a slightly sweet and garlicky flavor. They are often used in French cuisine, where their delicate taste enhances sauces, dressings, and vinaigrettes. Shallots can be used raw or cooked, and their mild flavor makes them perfect for dishes where a more subtle onion flavor is desired.

What are Cipollini Onions?
Cipollini onions are small, flat onions with a sweet, mild flavor. They are often used in Italian cuisine, where their natural sweetness is enhanced through roasting or caramelizing.
