Altitude significantly impacts various aspects of baking due to changes in atmospheric pressure and the boiling point of water. At higher altitudes, the atmospheric pressure decreases, which subsequently lowers the boiling point of water. This means that water will boil at a temperature lower than 100°C (212°F), which can affect the cooking and baking processes because many recipes rely on the boiling point of water being consistent.

The lowered pressure also affects how gases expand, which can lead to products rising more quickly and potentially causing issues such as overexpansion or collapse if not adjusted properly. Additionally, this can result in longer baking times as the reduced boiling point can influence moisture content and the way ingredients interact. Understanding these changes is crucial for adjusting recipes appropriately for altitude to ensure baked goods achieve the desired texture and doneness.
