Certificate of Kashrut


Our countertops may be kashered for Passover and maybe kashered from Diary to Meat (or vice versa). Kashering can be performed using water from a kli rishon, which should be directly poured onto the countertop.


Kosher Certification is the stamp of kosher approval by a rabbinic Agency verifying they have checked the products ingredients, production facility and actual production to ensure all ingredients, derivatives, tools and machinery have no trace of non kosher substances. The Kosher Certified symbol assures consumers that both the actual product and its production adhere to all Kosher Law requirements.
