Editing Fogou (section)

===Cold storage hypothesis===
Although in their present damp condition, use for food storage seems impractical,<ref name="Edwards"/> [[Diodorus Siculus]] stated that Iron Age people in Britain stored their grain in "underground repositories", adding contemporary evidence{{Dubious|date=February 2012}} to speculation that their main purpose was food storage.<ref name="Fox"/>
Where they were open at both ends, a fogou could provide suitable conditions for storing some foods, especially the drying of meat,{{Dubious|date=February 2014}} or storage of dairy products such as milk, butter, and cheese where natural moulds would assist in preservation of perishable foodstuffs.<ref>{{cite book |first=Jacqui |last=Wood |year=2001 |title=Prehistoric Cooking}}</ref>

Ashpits found at [[Trewardreva]] and in the circular side-chamber at [[Carn Euny]] were probably for preserving gulls' eggs, as was done on [[St Kilda, Scotland|Saint Kilda]] in Scotland. A layer of black greasy mould with charcoal, animal and bird bones at [[Treveneague]] is also very suggestive of food storage.{{Cn|date=May 2021}}
