Sweet Onion
Description
Sweet onions are a variety of onion known for their mild, sweet flavor, as opposed to the sharp, pungent taste of other onion types. They are larger and have a thinner, lighter-colored skin. Sweet onions can be recognized by their higher water content and lower sulfur content, which allows them to be sweeter to the palate. They are a favorite in both raw and cooked forms and can be measured in a variety of units, including ounces (oz), grams (g), pounds (lb), and kilograms (kg) for weight, as well as cups (c) and milliliters (mL) for volume, making them a versatile ingredient in both American and European recipes.

They are perfect for salads, sandwiches, and salsas where the onion's raw flavor can be appreciated. They are also ideal for caramelizing, which enhances their natural sugars and creates a rich, sweet taste suitable for a variety of savory dishes.
