Definition:
Bletting refers to the fact that some fruit must be allowed to fully ripen and start the decaying process before they are ready to eat. As Uncommon Fruits For Every Garden by Lee Reich points out, "Chemically speaking, bletting brings about an increase in sugars and a decrease in acids and tannins (tannins cause the unripe fruits to be puckery.)"
Fruits that need bletting:
- Medlar
- Some persimmons
- Quince
- Some Sorbus fruits
