High Altitude Changes Boiling Point and Baking
Lower atmospheric pressure at high altitude means water boils at a lower temperature — around 202°F (94°C) at 5,000 feet instead of 212°F (100°C) at sea level — so anything cooked by boiling (pasta, beans, simmered stews) takes longer to finish because the liquid itself is cooler even at a full boil. Baking is affected differently: lower air pressure lets gases in batter expand faster and moisture evaporate quicker, which is why high-altitude baking recipes often call for less leavening and a bit more liquid, not just a longer bake time.
