I have seen blanched, slivered almonds sold in packages. Hypothetically do these need a hechsher? I am aware that blanching involves heating so I imagine there could be kashrut concerns, but on the other hand this tweet from the CRC states that slivered almonds do not need a hechsher.

  • Offhand, it sounds like any alteration of a natural product requires a hechsher. I know that there are leniencies regarding using a cold knife such as cut up produce. But heating poses a lot more problems.

According to another tweet from the cRc, blanched almonds require certification.


According to the OU here, no hechsher is required for Pesah.
