Altitude Baking Adjustments
Above 3,500 feet, lower air pressure causes leavening gases to expand faster, liquids to evaporate quicker, and gluten to weaken. What works at sea level produces flat, sunken, or dry results at altitude. Enter your elevation for specific corrections.
Why altitude changes baking
At altitude, atmospheric pressure is lower, so: (1) CO₂ bubbles in leavened batter expand faster and larger — causing over-rise then collapse. (2) Water boils below 212°F (100°C) — liquids evaporate faster, drying out the structure. (3) Gluten sets more slowly because the structure is less firm. The solution: reduce lift, add liquid, increase structure, and raise oven temp slightly so the crust sets before overexpansion.
