bark

The hardships of bark-collecting in the primeval forests of South America are of the severest kind, and undergone only by the half-civilized Indians and people of mixed race, in the pay of speculators or companies located in the towns. Those who are engaged in the business, especially the collectors themselves, are called Cascarilleros or Cascadores, from the Spanish word Cascara, bark.

This softens the meat further, but at some loss of crunch to the bark.
