High altitude begins at approximately 3,500 feet or more above sea level. At high altitudes, there is lower atmospheric pressure, or air pressure, which changes the temperature at which water boils and how quickly leavening gases expand.
How does atmospheric pressure affect cooking at high altitude?
The key factor is declining air pressure at higher altitudes. Falling air pressure lowers the boiling point of water by just under 1 degree Fahrenheit for each 500 feet of increased elevation. The lower boiling point means water will cook off more quickly, and at a lower temperature.
Why does high altitude affect baking?
Low air pressure has two main effects on baked goods: They will rise more easily, and lose moisture faster; liquids evaporate more quickly since water boils at lower temperatures at high altitude. … It makes baked goods more prone to sticking. And sugar becomes more concentrated. Some cakes won’t set.
At what altitude is baking affected?
Elevation influences the internal temperature of cakes throughout the baking and cooling periods. Cakes may overflow pans and/or fall, cookies often spread excessively, and breads get fluffier when baked at geographical locations higher than 2,500 ft above sea level.
How does altitude affect baking bread?
High altitude (over 3,000 feet) affects bread baking because the lower air pressure allows the yeast to rise 25 to 50 percent faster, and the drier air makes the flour drier. If the dough over-rises, the results might be a heavy, dry loaf or misshapen or collapsed loaf.
How do you adjust baking time for high altitude?
High Altitude Baking — Good Rules of Thumb
- Oven Temperature. Increase by 15-25℉ …
- Baking Time. Decrease by 20-30% …
- Flour. Increase by 1 tbsp at 3,500 ft, and by 1 tbsp per 1,500 ft. …
- Sugar. Decrease by 1 tbsp per cup. …
- Liquids. Increase by 1 to 2 tbsp per 1,000 ft, and 1 ½ tsp per additional 1,000 ft. …
- Baking Powder/Soda. …
- Yeast.
Why does it take longer to cook an egg at high altitude?
Due to changes in atmospheric pressure, water boils at a lower temperature at higher altitudes than it does at sea level. This means that boiling eggs in a high-altitude region may require an increased cooking time (2).
How much longer do you bake at high altitude?
Changes at high altitude
Decrease by 5-8 minutes per 30 minutes of baking time. Baking at higher temperatures means products are done sooner. Increase by 1 to 2 tablespoons at 3,000 feet. Increase by 1 1/2 teaspoons for each additional 1,000 feet.
What occurs when cooking at high altitudes?
High altitude is defined as an elevation of 3,000 feet or more above sea level. Even at elevations of 2,000 feet, the temperature of boiling water changes from the standard 212°F at sea level to 208°F. Boiling or simmering foods at high altitude means lower temperatures and longer cooking times.
What is considered high elevation?
Heights from 5,000 to 8,000 feet are considered moderate; high altitude extends from 8,000 to 14,000 feet, very high altitudes from 14,000 to 18,000 feet, and extreme altitude beyond that. To give you some perspective, commercial airplanes maintain a cabin pressure of about 6,400 feet above sea level.
Is it OK to bake bread on a rainy day?
Nothing brightens the spirit more than the smell of freshly baked bread in the oven and it is a highly recommended cure for the rainy-day blues. In short, keep your dough warm and wet, keep yourselves warm and dry and make rainy days baking days!
What is considered low altitude for baking?
Newcomers to Wyoming’s mountain area, may wonder why potatoes take longer to cook or why cakes continually fall. Low altitude recipes usually need to be adjusted at altitudes above 3,000 feet. Time, temperature, and ingredients need to be adjusted.
How do you bake potatoes at high altitude?
How to Bake a Potato in the Oven at a High Altitude
- Scrub the potato thoroughly under cold water to remove any dirt on the skin. …
- Coat the potatoes lightly with a bit of olive oil and season with your choice of spices such as sea salt and black pepper.
- Pierce the potato in about four different places with a fork so steam can escape while cooking.
How does air pressure affect baking?
Changes in air pressure affect baking in these ways: Because water boils at lower temperatures, moisture evaporates quicker and can leave baked goods dry. … These gases expand quicker when baking at high altitudes, making baked goods rise and fall faster while in the oven, thus creating a dense or flat end product.
How do you adjust sea level for baking?
Follow this guide for baking at sea level:
- Lower the oven temperature by 10°C.
- For every 5ml (1tsp) baking powder, increase by 1 – 2 ml.
- For every 220g (1 cup) granulated sugar, increase by 15 – 3 ml ( 2 – 3 tbsp)
- For every 250ml (1 cup) liquid, decrease by 30 – 45ml (2 -3 tbsp)

Does dough take longer to rise at altitude?
High altitude affects the rising time of yeast bread doughs as leavening gases expand more quickly. Bread doughs double in size faster at high altitudes than at lower altitudes. The higher the altitude, the shorter the time required for dough to rise.
