Choke pear

A choke pear or chocky-pear is an astringent fruit. It is (the fruit of) any variety of pear that has an astringent taste and that is difficult to swallow. Similarly named trees with astringent fruits include the choke cherry (the common name for several species of cherry tree that grow in North America and whose fruits are small and bitter tasting: Prunus Virginiana, Prunus demissa, and Prunus serotina) and the choke plum.

La poire d'angoisse est un instrument de torture dont les origines remontent au Moyen Âge. Introduite dans la bouche, la vulve ou l'anus (suivant l'endroit où l'on avait péché) et pouvant augmenter de volume, elle étouffait les cris des suppliciés qui pouvaient troubler les juges, lors de l'Inquisition.
