For sous vide eggs, use a jar or a vacuum bag. Avoid cooking eggs loose in the water bath.
When cooking eggs sous vide, the goal is to maintain a consistent temperature throughout the egg. Cooking eggs loose in the water bath is not recommended because it's difficult to control the shape and consistency of the final product. Instead, you have two primary options:
Both methods prevent the egg from dispersing into the water and allow for precise temperature control, which is crucial for achieving the desired texture.
When using a jar, don't overfill it, and ensure it's heat-safe. Rapid temperature changes can cause some jars to crack. Preheating the jar slightly in warm water before adding the eggs can help prevent this.
