>At roughly nine thousand three hundred feet above sea level (~2800M)

I heard Antarctica on average very high above sea level. So I would think just the thinness of the air would make baking rather hard compared to sea level.

Sadly I will not be able go there. 40 years ago, when I when was at around 6000 feet above sea level on a trip, I was getting dizzy when moving around :) Sea level is were I was born and were I will stay.

The few times I've baked there, it's been a pretty good experience. There's a full height proving cabinet, yeast works really well at altitude, the ovens have steam injectors, there are good mixers, a commercial fryer. In many ways much easier than baking at home, but probably not a patch on a good bakery.

We almost ran out of sugar in 2021 and Rothera sent us a bag of Tate and Lyle in break-glass-in-emerhency box on one of the early transit flights the following summer. That's still hanging in the galley. Cream also goes pretty quickly, and forget about eggs. But you only need "egg product" anyway.

The foods that tend to be avoided are pasta and beans, or really anything which has to be boiled. There's a massive pressure cooker but it's a pain to use and clean. It's also hard to brew coffee if you tend to use off-the-boil. The best you'll get is about 93 C. Espresso is fine as its pressurised anyway.

Do they not do soaked beans? Leave them in water for 2 days and they shouldn't need a full boil I wouldn't think? Bonus: chickpea water as an egg substitute in recipes (powdered egg is nasty!). Re: coffee, mixing concentrated cold brew with hot water makes a pretty smooth cup

We'd definitely have kidney beans in chili and some other dishes, but I got the impression it was a hassle otherwise.

Friend and I ran a weekly pop-up espresso bar and did a lot of experimenting over the winter. The USAP "house" beans are quite dark, but at least they're roasted within a year or two because coffee is always available and we go through a lot of beans every season. Except the decaf. That stuff is decades old.

People often bring down a big bag from one of the roasters in Christchurch. We personally shipped down a lot of specialty coffee, mostly made V60 and aeropress. The outbuilding where our telescopes live also has a Chemex and an automatic.

Even if soaked, beans still take hours to cook without a pressure cooker.

I depends the beans and their freshness. If soaked and not 2yo+, it’s less than 1 hour for most of them. 30 min is enough for azuki and chickpeas if soaked 48h.

There’s other tricks: various beans can be found in the form of instant powder or flaskes (1 min watering - no cooking) semolina (5 min watering - no cooking) and pre steamed (no watering - 10/20 min cooking). I bring those to hike on the mountain and use gaz only to make them hot. Mixed with cereals semolina, spices, herbs and oil/nuts its the perfect submit meal.

		What's your recipe that uses semolina? I do a lot of outdoor activities and I'm always trying to find new foods to try

It should be noted that because of the effect of the poles on the atmosphere (the atmosphere is intrinsically thinner near the poles), the surface pressure is even lower, so that it feels like about 11k feet in altitude rather than 9k feet in altitude.
