Kashk

Kashk is a type of ration in Pathologic 2. It can be obtained by opening Packages, looting bodies, bartering with townsfolk or bought in groceries as well as the Broken Heart. It reduces hunger by 15%, but increases thirst by 10%.

Note that while kashk and eggs share identical hunger values and identical costs in stores, eggs increase thirst by a smaller amount (3%). As such, when given the option, eggs are an objectively better choice over kashk.
