The opening as it read in 2020

Birkat Hamazon ( , The Blessing of the Food), known in English as the Grace After Meals ( ; translit. bentschen or "to bless", Yinglish : Bentsching ), is a set of Hebrew blessings that Jewish Halakha ("collective body of Jewish religious laws") prescribes following a meal that includes at least a kezayit (olive sized) piece of bread .1 It is a mitzvah de'oraita (Aramaic: דְּאוׂרַיְיתָא ‎), that is written in the Torah (Deuteronomy 8:10).2 Birkat Hamazon is recited after a meal containing bread or similar foods that is made from the five grains , with the exception of bread that comes as a dessert ( pas haba'ah b'kisanin ) and food that does not possess the form or appearance of bread ( torisa d'nahama ), in which case a blessing that summarizes the first three blessings ( birkat me'ein shalosh ) is recited instead. It is a matter of rabbinic dispute whether birkat hamazon must be said after eating certain other bread-like foods such as pizza . Except when in teaching situations, Birkat hamazon is typically read individually after ordinary meals. Sometimes it's also sung aloud on special occasions such as the Shabbat and festivals .3 The blessing can be found in almost all prayerbooks and is often printed in a variety of artistic styles in a small booklet called a birchon (or birkon , ) in Hebrew or bencher (or bentscher ) in Yiddish . The length of the different Birkat hamazon can vary considerably, from bentsching under half a minute to more than 5 minutes.4 See the Rema's gloss, which defines what torisa denahama means. Pizza and birkat hamazon The shortest known Birkat Hamazon would be that in the Siddur of Saadia Gaon .
