New ingredients are added to your list of approved ingredients by submitting a New Ingredient Application. There are two ways to submit the application – by faxing or emailing the application and kosher letter to the OK office, or by the preferred method of submitting digitally through DigitalKosher (ensuring better tracking and real-time updates). Once the application is submitted, along with a valid kosher certificate for the ingredient, an OK rabbi will review the application. If the application is approved, the Data Entry department will enter the ingredient in our database which adds the ingredient to your list of approved ingredients.
