At high altitudes, atmospheric pressure is much lower than at sea level. This factor must be taken in account in baking. Many maunufacturers of flour, shortening and other baking ingredients will supply detailed information and adjusted formulas for any given location. In general, the following adjustments must be made above 2000 or 3000 feet elevation.
2500ft 5000ft 7500ft Baking Powder -DECREASE 20% 40% 60% Flour -INCREASE - 4% 9% Eggs -INCREASE 2-1/2% 9% 15% Sugar -DECREASE 3% 6% 9% Fat -DECREASE - - 9% Liquid -INCREASE 9% 15% 22% To make adjustments, multiply the percentage indicated by the amount of ingredient and add or subtract the result as indicated.
Example : Adjust 1 lb (16 oz ) Flour for 7500 ft. .09 x 16 oz = 1.4 oz 16 oz + 1.4 oz = 17.4 oz
Hope this will assist.
