What extra step is recommended for home preparers unsure of initial cleaning?

Answer

Gentle singeing over a low flame

For home preparers who are uncertain about the thoroughness of the initial cleaning process, an additional layer of assurance against unseen irritants is recommended. This involves gently singeing the surface of the fruit or pad over a low flame or a very hot, dry pan, which helps to burn off any microscopic glochids that might have survived prior scraping efforts, followed immediately by rinsing.
