A pear can look like a botanical beauty on the outside, then reveal a mushy, brown surprise when the knife reaches the center. That frustrating problem happens because pears naturally ripen from the core outward, so the inside can become soft and overripe while the surface still looks perfectly respectable.
The trick lies in knowing that a pear does not behave like an apple. Most European pears actually prefer to finish their ripening after harvest, and letting them sit on the tree until they feel soft can lead to coarse texture, poor flavor and internal breakdown.
