Did you know if you live at a high altitude you will need to adjust the oven temperature and baking time on a recipe?
Air pressure decreases at high altitudes. With lower air pressure, liquids evaporate faster, liquids to boil at a lower temperature, and leavening agents like baking soda and baking powder expand and react more quickly than at higher air pressures found at sea level.
Without adjusting baking time and temperature at high altitudes, your baked goods will probably dry out, rise too soon, and have air spaces and holes that make them lack structure and consistency.
A good rule of thumb for time and temperature adjustments at high altitude are to increase the temperature by 20 degrees Fahrenheit and decrease baking time by 5-8 minutes per 30 minutes of baking.
