How big should mung bean sprouts be before eating them?

Mung bean sprouts are typically ready to eat when they reach a length of about 2 to 4 inches (5 to 10 centimeters). At this stage, they are crunchy and have developed a mild flavor, making them ideal for culinary uses. Sprouts can be harvested as soon as the first leaves appear, usually within 5 to 7 days of sprouting. It's best to consume them before they grow too long, as they can become tough and less palatable.
