Does “kosher” mean a rabbi blessed the food?
No. There is no blessing a rabbi (or any person for that matter) can say to make food kosher. The term “Kosher” refers to the fact that all of the ingredients within a given product (or process of production) are Biblically and Rabbinically permitted. Kosher food is initially defined in the Torah. Permitted animals have to be slaughtered (and then soaked and salted) in a certain way to make their meat kosher. The role of the kosher supervisor is to ensure that all of the ingredients and a process. Jewish people do, however, say a blessing before they eat and at the conclusion of the meal.
