531. The Order of Brachos
Brachos 8:12
When it comes to all these brachos on food, if there is a doubt as to whether or not one recited the bracha, he does not repeat - neither with a bracha before eating nor with a bracha after eating - because these brachos are of rabbinic origin (and therefore we act leniently in a case of doubt). If someone absentmindedly put food in his mouth without reciting a bracha, he proceeds as follows: if it’s a beverage, he should swallow it and then recite the bracha; if it was a fruit that would be repulsive to remove from his mouth, such as berries or grapes, then he should move them to the side of his mouth, recite the bracha and swallow; if it’s a food that would not be repulsive, such as beans or peas, then he should remove them, recite the bracha with his mouth empty, and then eat them.
Brachos 8:13
If a person has several different types of food in front of him, the procedure is as follows: If they all take the same bracha, he recites the bracha on one and it covers all of them; if they take different brachos, he should recite the appropriate bracha on each one. The order of the brachos depends on which food he prefers. If he doesn’t particularly prefer one of the foods, the order of the brachos is as follows: if any of the foods are of the seven special species Israel, the bracha is recited over them first. Among those species, we follow the order in which they are mentioned in Deuteronomy 8:8: wheat, barley, grapes, figs, pomegranates, olives and dates. When it comes to dates and grapes, however, dates come first. This is because dates come closer to (the second occurrence of) the word “land” in that verse than grapes do (to the first occurrence of “land”).
