You can achieve different egg textures with sous vide by adjusting the water bath temperature. Lower temperatures (around 63-65°C or 145-149°F) result in a gel-like yolk and a very soft white, while higher temperatures (around 75-82°C or 167-180°F) produce a firmer, more cooked egg.
Sous vide cooking allows for precise temperature control, which is crucial for achieving specific egg textures. Here's a breakdown of how temperature affects the final result:
Gel-like Yolk and Soft White (63-65°C / 145-149°F): Cooking eggs at this temperature range for about an hour results in a custard-like yolk and a very delicate, almost runny white. The yolk will be thick and creamy, perfect for serving on toast or salads.
Soft-Set Yolk and Semi-Firm White (68-70°C / 154-158°F): This temperature range yields a yolk that is still runny but slightly thicker than the previous range. The white will be more set but still tender.
Firm Yolk and Firm White (75-82°C / 167-180°F): Cooking eggs at these higher temperatures will result in a fully cooked yolk and a firm white, similar to a hard-boiled egg, but with a smoother texture. The cooking time will vary depending on the desired firmness.
Remember that cooking times can vary slightly depending on the size and freshness of the eggs, as well as the accuracy of your sous vide equipment. It's always a good idea to experiment to find your preferred texture.
When cooking eggs sous vide, consider adding a tablespoon of vinegar to the water bath. This can help prevent the egg whites from leaking out if the shell cracks during cooking.
