How to store White sauce

To store roux sauce properly, allow it to cool down to room temperature before transferring it to an airtight container. Place the container in the refrigerator and ensure that the lid is tightly sealed. Stored in this way, roux sauce can last for up to 3-4 days in the refrigerator.

If you want to store roux sauce for a longer period, it can be frozen. Allow the sauce to cool down to room temperature before transferring it to a freezer-safe container. Leave a little room at the top of the container to allow for expansion during freezing. Cover the container with a lid and label it with the date before placing it in the freezer. Roux sauce can last up to 3 months in the freezer.

When you are ready to use the roux sauce, defrost it in the refrigerator overnight. It is important to avoid defrosting the sauce on the counter, as this can cause bacteria growth. Once the roux sauce is thawed, you can reheat it on the stove or in the microwave until it reaches the desired temperature.

How to reheat bechamel sauce

There are a few different methods for reheating roux-based sauces, depending on the amount you are reheating and your personal preference. Here are three common methods:

Stove: Reheating roux sauce on the stove is a good option if you have a larger quantity to reheat. Simply place the saucepan with the roux sauce over low heat and stir continuously until it is heated through. Be careful not to let it boil, as this can cause the sauce to separate.

Microwave: If you have a smaller amount of roux sauce to reheat, using a microwave can be a quick and easy option. Transfer the roux sauce to a microwave-safe container and heat it in 30-second intervals, stirring in between, until it is heated through. Be sure to use a microwave-safe lid or cover the container with a paper towel to prevent splatters.

Bain-marie: If you want to reheat roux sauce without the risk of it burning or separating, a bain-marie (water bath) is a good option. Simply place the container with the roux sauce in a larger pot or saucepan filled with hot water. Heat the water over low heat and stir the roux sauce occasionally until it is heated through.
