High Altitude Adjustments

mountain range

The change in atmospheric pressure at high altitudes makes it necessary to adjust recipes and oven temperatures to achieve successful results. General guidelines should be followed when making baking adjustments.

Water 

Water boils at a lower temperature in high altitude and evaporates quicker. Liquids should be increased to prevent the product from drying out

Water Boiling Temperature Chart
Altitude Temperature
Sea Level 212 F (100 C)
2,000 ft 208 F (97.8C)
5,000 ft 203 F (95 C)
7,500 ft 198 F (92 C)

Leaveners

Leavening gases expand quicker. Amounts of chemical leavener should be reduced and oven temperature should be raised by about 25 degrees to set air cells faster.

Flour

Flour absorbs larger quantities of liquids so increasing the amount holds up to a higher liquid quantity. Increased amounts of flour also builds a stronger structure and sets the batter quicker so items do not collapse.

Sugar

Amounts should be decreased to prevent a baked good that is over tender and has weak structure.

Egg

Quantities need to be increased to provide a strong structure in a baked good.

Baking pans

Should be greased heavier to prevent sticking and wrap finished baked goods air tight as soon as they are cool because products have a shorter shelf life at higher altitudes

Baking times should be reduced since the liquids in a recipe evaporate faster at high-altitudes and the product will dry out quicker. The oven temperature should also be increased to help quickly set the structure so the item does not collapse
