Mowed Lawn Aroma
A flavor, like a musical chord, is made of a set of notes. The fullness of a flavor is the result of the interplay between the numerous chemical components that constitute the flavor’s profile.
A flavorist creating a fruity flavor – let’s say, peach flavor for an ice cream –will usually need a “green” or botanical note to round out the flavor. One of the popular chemicals used by flavorists to impart “greenness” is called cis-3-hexenol. A whiff of pure cis-3-hexenol reminds one of a freshly mowed lawn.

There is no need for the 3 days to be consecutive.

K’bolo kach polto – Some Rishonim1 understand that since the issur was absorbed through kevisha it can be purged with kevisha.
