Boiling Points. Everyone has boiled water at some point so everyone has a basic understanding of what is meant by boiling. We put a pot on the stove, go away for ten minutes, and come back to find the water boiling vigorously, ready for the pasta, eggs, or oatmeal to be put in. One of the most significant changes that occur in high altitude areas concerning cooking is the boiling point of water. Your pot of water will come to a boil sooner as it will boil at a lower temperature than at sea level. You would boil your food longer because it is boiling at a lower temperature.At elevations higher than 3,000 feet, you may start to notice the difference though. At sea level, water boils at 212 F but it only needs to reach 207 F to boil at 3,000 feet. At 5,000 feet, bubbles start to break the surface at around 203 F, and at 7,500 feet, at 198 F.

The boiling point of a substance is the temperature at which it can change its state from liquid to gas throughout the bulk of the liquid at a given pressure. Thus, for example, the boiling point of water is lower at a high altitude than it is at sea level, because the air pressure at high altitudes is lower than...
