Eat a doughnut fried to a recipe that only works at 14,115 feet
Same recipe since 1916
Doughnuts fried at the top of a fourteen-thousand-foot mountain, to a 1916 recipe adjusted for the air pressure at that height.
Why it's unique
The summit house has fried doughnuts to the same recipe since 1916, and the recipe is calibrated for the air pressure at 14,115 feet. Water boils far below 100C up here, so the dough behaves differently and the frying behaves differently. The same ingredients at city altitude produce something else entirely.
That is the rubric's only-feasible-here category almost literally: not a local speciality that happens to be made here, but a food that cannot be reproduced below because the physics of cooking it change with the altitude. The operator is the City of Colorado Springs rather than a private concession, which is part of why the recipe has survived unchanged.
Before you go
Buy them at the summit and eat them at the summit. People carry them down and report they are not the same thing, which is the entire point rather than a disappointment.
The summit is routinely 30 to 40F colder than the city and altitude sickness is real at 14,115 feet, so go slowly, drink water, and eat something. You can get up by the cog railway from Manitou Springs, by the Pikes Peak Highway toll road, or on foot up Barr Trail; all three are weather-dependent and the road and railway both close.
