Step-by-step method
- Use egg whites that are fresh and free from any trace of yolk.
- Pour them into a clean freezer-safe container, leaving a little space at the top, or divide them into small measured portions.
- Seal tightly and label the container with the date and the number of whites or amount.
- Freeze promptly and use within about three months for the best quality.
- Thaw the portion in the fridge rather than at room temperature.
- Use thawed whites in baking, meringue or another thoroughly cooked recipe; do not cook them directly from frozen.
Can frozen egg whites still make meringue?
They can be useful for meringue once thawed, provided the whites were separated cleanly and the bowl and beaters are free from grease. Let the whites thaw in the fridge, then follow the recipe’s instructions for bringing them to the right temperature before whisking.
How should you portion egg whites for the freezer?
Freeze them one white at a time or in the amount your usual recipe needs. Label the container clearly, because egg-white size varies and a measured portion is easier to use accurately in baking.
What should you avoid when freezing egg whites?
Avoid freezing whites that have been left out for a long time, mixing them with yolk, or using a container that is not clean and airtight. Those details make the portion less reliable for whipping and baking.
