What it is
A Monte San Giacomo potato, including the local Patan’ ri fuos form preserved underground in fern-lined pits.
Origin place card
Production is documented in Monte San Giacomo, in small mountain plots above 750 m.
Verified history
The source says the cultivation is perpetuated from time immemorial and the pit technique was once used by everyone to preserve seed and avoid difficult transport downhill. Treat this as source-supported tradition/history from Regione Campania — Patata di Monte San Giacomo; the current evidence does not independently establish a founder, precise origin date, first attestation, or archival origin beyond that source framing.
Local hypothesis
This is potato as architecture: holes, ferns, winter freshness, and the mountain refusing the valley’s storage rules.
Local legend / oral tradition
No legend documented; oral tradition should focus on pit selection and family seed.
Ingredients
Yellow-flesh, white-flesh and red potatoes grown without irrigation in sedimentary mountain soils. Source-supported detail: Per la tipologia "Patan ri fuos", vengono scavate delle grandi buche ai margini dei campi di coltivazione, rivestite di felci, riempite di patate e interrate nuovamente.
Method
Prepare fields in autumn, sow manually May to mid-June, weed and ridge, harvest mid-August to mid-September; for Patan’ ri fuos, line large field-edge pits with fern, fill with potatoes and rebury. Source-supported detail: Per la tipologia "Patan ri fuos", il prodotto conserva la freschezza di un prodotto appena raccolto in epoche in cui i tuberi portati a valle e conservati in modo tradizionale mostrano i segni della disidratazione o l'emissione dei germogli.
Ritual / calendar
Quando tutte le piante sono emerse dal terreno si procede con sarchiature manuali per eliminare le erbe infestanti e contemporaneamente si effettua il rincalzo.
Why travel for it
A buried-mountain-potato page: terrapuglia soils above 750 m, no irrigation, patan’ ri fuos stored in fern-lined pits so the tubers stay fresh when valley potatoes sprout.
Recreate-it pathway
Recover pit-preserved potato uses and compare with ordinary stored potatoes before writing recipe claims.
Editorial warning
Keep Patan’ ri fuos as the local conservation subtype; crosslink to Patata sotterrata di Calvaruso but do not merge them.
Fieldwork questions
Which families still dig the pits? Are the fern species and pit locations inherited knowledge?
