Crunchiness

Crunchiness is the sensation of muffled grinding of a foodstuff.

Crunchiness differs from crispness in that a crisp item is quickly atomized, while a crunchy one offers sustained, granular resistance to jaw action.

Crunchy foods are associated with freshness, particularly in vegetables.

[1][2] In bready foods, crunchiness can instead be associated with staleness.

Other foods regularly associated with the sensation include nuts[3] and sweets.
