The Roof of the World Ration

Why this dish? On 29 May 1953, en route to the summit, Hillary ate what was light to carry and rich in calories: biscuits, cheese, chocolate, smoked bacon, hot soup, and very sweet tea. Above 7,000 m, appetite collapses and every bite had to be forced down.

High-altitude ration

A reconstructed expedition "plate": crackers spread with hard cheese, strips of grilled bacon, squares of dark chocolate, all warmed by a mug of soup. Not a gourmet dish, but the exact fuel that hoisted a man to 8,849 metres.

You know, up there, eating becomes a job like any other — and not the easiest. At that altitude, your stomach doesn't want to know, so you choose what weighs little and feeds a lot: biscuit, a bit of cheese, chocolate, a slice of bacon. Tenzing and I would melt snow for hours just to get a mug of soup and a good sweet tea. You didn't eat for taste, old chap, you ate to keep climbing.

Ingredients
  • Hard tack (expedition crackers)a handful (caloric base, carbohydrates)
  • Hard cheesea wedge (fat and protein, keeps well)
  • Smoked bacona few slices (fat, salt, dense energy)
  • Dark chocolatetwo squares (quick sugar, morale)
  • Dehydrated soupone packet (warmth and rehydration)
How it was made : On the 1953 British expedition, supplies were designed for weight and calories: about 4,000 calories per day were planned, but at altitude men consumed much more fighting the cold. Dehydration was enemy number one: litres of hot liquid were needed, hence the obsession with tea and soup.
