What specialized cleaning technique uses brief exposure to an open flame for Opuntia fruit?

Answer

Holding the fruit briefly over an open flame to singe off glochids

One of the two primary methods recommended for external cleaning of Opuntia fruit, particularly for dealing with the invisible glochids, involves the application of controlled heat. This technique requires briefly holding the fruit over an open flame, such as a gas burner. The purpose of this direct heat application is to instantly singe off the fine glochids. Caution must be exercised during this process, as overheating the fruit can negatively affect the skin and underlying flesh, indicating that precision is necessary to remove the physical defenses without cooking the fruit prematurely.
