Mountaineers find it time-consuming and difficult to brew a good cup of tea or cook food, especially as they climb higher. You just can’t make your usual cup that cheers on the top of Mount Everest.
Water normally starts boiling when it reaches a temperature of 100 (or 212 ). But this is true only if you are at sea level. As you go higher, due to a fall in the atmospheric pressure, water starts boiling at a lower temperature. (70 or 158 on the summit of Mount Everest!)
This heat is not enough to extract the best flavour from the tea leaves. Cooking in a saucepan or pressure cooker also takes much longer on mountain tops.
