Cooking Kosher: French Onion Chicken



The Hebrew word “kosher” means fit or proper as it relates to Jewish dietary law. Kosher foods are permitted to be eaten and can be used as ingredients in the production of additional food items.

And when it comes to Kosher cooking, there is a lot to learn, a lot to share, a lot to try, and a lot to eat. The St. Louis Jewish Light is partnering with a fun Facebook group called Adventures In Kosher Cooking and its admin Howard Wasserman to provide more insight and especially more recipes to those of you looking to keep your kosher choices abundant.
