The best way to stop the cooking process after sous viding eggs is to immediately transfer them to an ice bath (a mixture of ice and water) for at least 15 minutes. This rapidly cools the eggs and prevents further cooking.
Sous vide cooking involves precise temperature control, but the residual heat within the egg can continue to cook it even after it's removed from the water bath. To achieve the desired texture and prevent overcooking, a rapid cooling process is crucial. Here's a step-by-step guide:
Prepare an ice bath: Fill a bowl with plenty of ice and cold water. The water should be cold enough to maintain a low temperature throughout the cooling process.
Carefully remove the eggs from the sous vide water bath. Be cautious, as they will be hot.
Immediately submerge the eggs in the ice bath. Ensure they are fully covered by the ice water.
Let the eggs sit in the ice bath for at least 15 minutes. For larger batches or thicker-shelled eggs, you may need to extend the cooling time to 20-30 minutes.
After cooling, the eggs can be gently cracked and served immediately, or stored in the refrigerator for later use.
Don't skip the ice bath! Even if you plan to eat the eggs right away, the ice bath helps to firm up the whites slightly, making them easier to handle and peel (if you're making soft-boiled style eggs).
