In this highly technical article from Aish.com, Rabbis Chaim Gross and Shraga Simmons explain the sources, structure, and intricate halachot (laws) of reciting Bircat Hamazon according to Orthodox Judaism. Part of the “Crash Course in Jewish Blessings” series, this article would be useful for those seeking a practical guide to the minute details of how and when to recite Bircat Hamazon, including how much bread needs to be consumed and how quickly it needs to be eaten. Although it provides anecdotal examples and a complete audio recitation of the Grace After Meals, due to the technical language and style of this article, it is intended for those who have a strong background in Jewish law and learning.
