Airtight glass containers or freezer-safe plastic containers with tight-fitting lids are best for preserving the color and aroma of stored gravies. These materials prevent oxidation and absorption of odors.
When storing gravies, the goal is to minimize exposure to air and prevent the absorption of unwanted flavors. Oxidation can cause the gravy to darken and lose its vibrant color, while exposure to air can also diminish its aroma.
Here's a breakdown of why certain containers are preferred:
Airtight Glass Containers: Glass is non-porous, meaning it won't absorb odors or flavors from the gravy. Airtight lids create a seal that prevents air from entering, preserving both color and aroma. Look for jars with rubber gaskets or clamp-style closures for the best seal.
Freezer-Safe Plastic Containers: If you plan to freeze the gravy, use plastic containers specifically designed for freezer use. These containers are more durable and less likely to crack at low temperatures. Ensure the lids fit tightly to prevent freezer burn and maintain the gravy's quality.
Avoid Reactive Materials: Avoid storing gravy in containers made of reactive metals like aluminum or copper, as these can interact with the gravy and alter its flavor and color.
Proper storage also involves cooling the gravy completely before transferring it to the container and refrigerating or freezing it promptly. This minimizes the risk of bacterial growth and further preserves its quality.
To further protect the gravy's surface from oxidation, place a piece of plastic wrap directly on the surface of the gravy before sealing the container. This creates an extra barrier against air exposure.
