What is an outdone egg in a recipe?

An outdone egg in a recipe refers to an overcooked egg, which has typically become tough and rubbery. This can happen when eggs are boiled too long or cooked at too high a temperature. The result is often a dry texture and a greenish-gray ring around the yolk, indicating that the proteins have overcoagulated. To achieve the best results, it's essential to monitor cooking times and temperatures closely.
