To boil soup on an induction cooker, the general guideline is to bring the soup to a boil, which typically takes around 10 to 15 minutes. This duration can vary depending on the initial temperature of the soup, the power setting on the induction cooker, and the specific recipe. Induction cookers heat food more efficiently than traditional electric or gas cooktops, as they use electromagnetic fields to directly heat the pot, resulting in faster and more precise temperature control.

The efficiency of induction cookers is attributed to their ability to quickly transfer heat to the pot, which in turn heats the soup more rapidly. According to a study published in the Journal of Food Science, induction cookers can reduce cooking times by up to 30% compared to conventional electric cooktops. This is due to the fact that induction cookers maintain a more consistent temperature throughout the cooking process, minimizing heat loss and ensuring that the soup reaches the desired boiling point faster. Additionally, the rapid heating allows for better flavor development and preservation of nutrients in the soup.
