Key Ingredients

labelled ingredients for scallion oil: green onions and oil.
  • Scallions (Green Onions): Scallions are the star ingredient of scallion oil, imparting a fresh, oniony flavor and vibrant green color. They are used for their aromatic essence, which infuses the oil during cooking, creating a savory and fragrant condiment. When selecting scallions for scallion oil, opt for fresh, firm ones with crisp green tops, as they will yield the best flavor and color. If scallions are unavailable, chives or leeks can be used as substitutes, although they may impart slightly different flavors.
  • Oil: Oil serves as the base for scallion oil, providing a medium for frying the scallions and extracting their flavors. Neutral oils such as vegetable oil, canola oil, or peanut oil are commonly used, as they allow the flavor of the scallions to shine without overpowering other ingredients. It’s best to choose an oil with a high smoke point to prevent it from burning during the frying process. Additionally, using a light-colored oil helps maintain the vibrant green color of the scallions. Avoid using strongly flavored oils like olive oil, as they can compete with the delicate flavor of the scallions.
  • Salt (optional): Salt is added to scallion oil to enhance the flavors of the scallions and oil, providing a balanced seasoning to the condiment. When seasoning scallion oil, start with a small amount of salt and adjust to taste, as the saltiness can vary depending on personal preference.

How to Store

Allow the scallion oil to cool to room temperature after preparing it. This prevents condensation from forming inside the storage container, which can lead to spoilage.

Transfer the cooled scallion oil to a clean, dry glass jar or airtight container with a secure lid. Ensure the container is completely dry to prevent moisture from contaminating the oil.

Refrigerate: Store the scallion oil in the refrigerator to prolong its shelf life. The cool temperature helps preserve the freshness of the oil and prevents it from turning rancid. Scallion oil can typically be stored in the refrigerator for up to several weeks.

Avoid Freezing: While scallion oil can be refrigerated, it is not recommended to freeze it. Freezing can alter the texture and flavor of the oil, resulting in a less desirable taste and consistency.
