You dry out egg whites by aging them in the refrigerator.
Aging Egg Whites
The primary method to dry out egg whites is through a process called aging. This doesn't involve any complex procedures but simply allowing the egg whites to sit in the refrigerator, uncovered, for a period of time. Here's how you can do it:
-
Separation: Carefully separate the egg whites from the yolks, ensuring no yolk gets into the whites.
-
Container: Place the egg whites in a clean, shallow bowl or container. A shallow container maximizes surface area, which facilitates the drying process.
-
Refrigeration: Put the container of egg whites in the refrigerator, uncovered. This allows the moisture in the whites to evaporate gradually.
- Duration: The ideal duration can vary, but letting them sit for a few days, as suggested by the provided reference, is often sufficient. (12-Dec-2022).
Why Dry Out Egg Whites?
Drying out egg whites, a process referred to as aging, has several benefits, especially for baking:
- Reduced Water Content: Aging reduces the water content in egg whites.
- Looser Proteins: This process makes the proteins in the egg whites looser.
- Enhanced Stability: The combination of less water and looser proteins leads to a stronger and more stable meringue, a crucial aspect for recipes like macarons. (12-Dec-2022)
In summary, the process of drying out egg whites is done by simply aging them in the fridge, which enhances their stability and texture, especially for baking.
