Yes, onions are commonly used in Chinese cuisine. Onions, along with other aromatics like garlic and ginger, play a fundamental role in many Chinese dishes, providing flavor, aroma, and depth to various recipes.
While onions are indeed used in Chinese cooking, it's worth noting that Chinese cuisine encompasses a wide range of regional styles and flavors. Different regions within China have their own unique culinary traditions and ingredient preferences. In some specific dishes or regional cuisines, onions may be used more sparingly or substituted with other ingredients depending on the flavor profile desired.
For example, in certain Chinese dishes, green onions (scallions) are used instead of regular onions to provide a milder, fresher flavor. Green onions are particularly popular in dishes like stir-fries, soups, and garnishes.
It's important to remember that the diversity of Chinese cuisine means that ingredient usage can vary significantly based on regional and personal preferences, so there isn't a single fixed rule for the use of onions.
