Apparatus and method for generating steam

A method of controlling the pressure of steam in a steam generating apparatus comprising:

• a body for receiving water to be heated and comprising a first portion comprising a first metal;
• a heating device comprising a second portion comprising a second metal,
• the body being connected with a heating plate of the heating device by forming an intermetallic layer between the first portion and the second portion, and
• a temperature sensor for measuring a temperature that is indicative of a pressure inside the body, the temperature sensor being arranged in thermal contact to the heating device outside the body, the method comprising the steps:
• setting the target water temperature for a first time period to a first set temperature;
• setting the target water temperature for a second time period to a second set temperature higher than the first set temperature;
• setting the target water temperature for a third time period to a third set temperature lower than the second set temperature.
