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.

This is based on the ruling of the Rama (Y.D. 113:7) that if a non-Jew lit his fire from a fire that was lit by a Yisroel, then the food cooked with that fire would not be subject to the issur of bishul akum.

Rav Moshe zt”l’s Heter of Cholov Stam Revisited

Halacha states that milk which is produced without hashgacha (r’iyah of a Yisroel) is non-kosher; such milk is termed “cholov akum”. This rule is a gezeirah, lest milk from non-kosher animals be mixed into what otherwise could be assumed to be kosher milk.
