Pringles 2017

Calf Rennet Clarification:
Rennet per se, is not impermissible.
It is permissible to eat cheese which has rennet from calf rennet though
praiseworthy to refrain from due to a slight difference of opinion viz:

Is Whey Rennet Haraam? (no!)

Alcoholic Flavourings Clarification:
Alcohols used as a carrier for food colourings and flavourings are permissible as long as they are not sourced from dates or grapes.
