High Altitude Cooking Quiz: Why Water Boils Cooler Up High

This high altitude cooking quiz heads up the mountain to make dinner. Play 10 interactive questions on lower air pressure, water boiling below 100 C, a drop of roughly 1 C for every 300 metres, pasta and eggs taking longer, pressure cookers fixing the problem, cakes rising too fast, adjusting leavening, liquid and oven heat, Denver's mile-high kitchens and Everest's barely hot tea.

Explanations: answer key for all 10 questions

Q1: Why does water boil cooler at high altitude?
Answer: Air pressure is lower
Less pressure lets water boil sooner.
Q2: At what temperature does water boil at sea level?
Answer: 100 C
That is 212 F.
Q3: Roughly how much does the boiling point drop per 300 metres?
Answer: About 1 C
It is an approximation.
Q4: Why does pasta take longer to cook up high?
Answer: Boiling water is cooler
Cooking time increases.
Q5: Which pot helps solve the problem?
Answer: A pressure cooker
It raises the boiling point.
Q6: What can happen to cakes at high altitude?
Answer: They rise too fast and collapse
Gases expand more easily.
Q7: What do bakers often reduce at high altitude?
Answer: Baking powder or soda
Less leavening prevents collapse.
Q8: Why do recipes add a little more liquid up high?
Answer: Moisture evaporates faster
Dry air pulls water away.
Q9: Which US city is called the Mile High City?
Answer: Denver
Its cooks know these tricks.
Q10: Why is tea on top of Everest disappointing?
Answer: Water boils far below 100 C
It boils at around 70 C.

Cooking Where the Air Is Thin

At high altitude, air pressure is lower, so water boils at a lower temperature. At sea level water boils at 100 C, but the boiling point drops roughly 1 C for every 300 metres of height. On top of Mount Everest, water boils at around 70 C, making a disappointing cup of tea.

Because boiling water is cooler, pasta, beans and boiled eggs take longer to cook. Pressure cookers solve the problem by raising the pressure and the boiling point, which is why they are popular in mountain towns.

Baking changes too. Gases expand more easily, so cakes can rise too fast and collapse, and moisture evaporates faster. Bakers often reduce baking powder or soda, add a little more liquid and raise the oven temperature slightly. Cooks in Denver, the Mile High City, know these tricks well.
