Buzón also explained how tiger nuts are cultivated in L"Horta Nord. It"s a slow, meticulous process that begins with planting between March and May, when temperatures are gentler with lots of humidity. Tubers are then collected from November to January with a harvester, after which the ground is burned to manage further spread: considered an invasive species (and a weed in much of the world), Cyperus esculentus must be carefully managed. Once washed, the tiger nuts are dried for about three months in specially ventilated buildings known as "cambras" before being manually sorted to remove any damaged specimens or impurities.
