If one blessed Creator of ground produce on tree produce, one has fulfilled one's obligation. If one blessed Creator of tree produce on ground produce, one has not fulfilled one's obligation. Therefore, if one is in doubt of the type of fruit - whether it is tree produce or ground produce, one blesses Creator of ground produce. And, on everything, if one blessed Through Whose word everything was created, one has fulfilled one's obligation, even on bread or wine.
היו לפניו פרי האדמה ופרי העץ ובירך על פרי האדמה ונתכוין לפטור את פרי העץ יצא:
All of these blessings [on food and beverages] need to not interrupt between blessing and eating (or drinking), and one needs to make the blessing(s) audible; and if one does not make it audible, one has fulfilled one's obligation, as long as the words depart from one's lips. And the blessings can be spoken in any language. And one should not bless nakedly until one covers one's genitalia. What are speaking about? With a man. But, with a woman, she may sit with her lower genitalia being covered by the ground, since this covers her genitalia. And even if he is not naked, but if his heart does not see his genitalia or that his head is uncovered, it is forbidden for him to bless.
Everything upon which one blesses - to eat something or to smell something [or to drink something] - requires grasping the object with one's right hand when one blesses.
We only bless upon food or beverage once it is brought in front of the person. When one blesses and then they bring the food or beverage in front of the person, the person needs to bless anew upon this food or drink. But one who blesses upon fruits in front of the person and then they bring further fruits of that type or from another type which is of the same blessing as the blessing of the first item, one need not bless again. Gloss: And it's good to be careful from the outset to have one's mind on which beverages and/or foods they will be bringing to the person [so as to avoid generating new blessings for unexpected foods].
...One who is standing by an aqueduct, one blesses upon the water annd drinks the water, even though the water that one is drinking was not in front of the person when the person blessed upon it, since the person had intended to drink from the flowing water from the outset....
