How to Store / Freeze This Sauce
Allow the white sauce to cool completely before storing. This prevents condensation, which can make the sauce watery.
Transfer the cooled sauce into an airtight container. Glass containers with tight-fitting lids are ideal for maintaining freshness.
Label the container with the date of preparation. This helps you keep track of its shelf life.
Store the container in the refrigerator. The white sauce will keep well for up to 5 days.
For longer storage, consider freezing the sauce. Pour the cooled sauce into a freezer-safe container, leaving some space at the top to allow for expansion.
Alternatively, you can use ice cube trays to freeze the sauce in smaller portions. Once frozen, transfer the cubes to a freezer bag for easy portioning.
When ready to use, thaw the sauce in the refrigerator overnight. If you're in a hurry, you can use the defrost setting on your microwave.
Reheat the sauce gently on the stovetop over low heat, stirring frequently to prevent it from separating. If the sauce appears too thick, add a splash of unsweetened almond milk to reach the desired consistency.
Avoid reheating the sauce multiple times, as this can affect its texture and flavor. Only reheat the amount you plan to use immediately.
If you notice any off smells, discoloration, or mold, discard the sauce immediately. Food safety is paramount.
