Hafrashas Challah
42. Giving out to others. A woman who bakes pastries or challos to give out to others in mishloach manos should not make a brochoh upon taking off challah – even if she bakes the minimum amount of dough – since she is baking to give out to others (שו"ת מנח"י ח"י סי' ק"ב ), unless she keeps the minimum amount for hafrashas challah for herself (עי' מש"כ באריכות גליון חוקי חיים 67).
43. Receiving baked goods. One who receives baked goods from others should make sure not to put all the same types of products together in one container or in the freezer, as this is like combining things which add up to the minimum amount for hafrashah in one basket. This creates a question if he needs to take off challah, which can in turn lead to him separating from food which is patur for food which is chayav, in such a way that some get challah separated and some do not.
Tevilas Keilim
44. One may send food to his friend in a non-toiveled dish since, for him, it is considered a “commercial dish,” not a dish for eating. However, he should make a note to the recipient that the dish requires tevilah (אהל יעקב דיני טבילת כלים אות ע"ו ).
45. Not all poskim agree that the giver can toivel the dish for the recipient even if he wants to, since for him, the dish is will be used as a gift, not for eating, and perhaps there is not a chiyuv tevilah on the dish yet. This is especially true of a valuable dish, where his whole intention is to give it as a gift (מקור חיים סי' י"ד עמ' 40, שו"ת תשוה"נ ח"א סי' תנ"ב ).
