If someone has a Kezayit of cake, for example, and he finishes it without having blessed before eating it, does he make an after-blessing?
If your breath smells of garlic, would you solve the problem by eating more garlic???– Double AA ♦Sep 1, 2013 at 23:30
@DoubleAA I think I remember once a Talmid Hacham telling me that you should make a Beracha Aharona.– Hacham GabrielSep 1, 2013 at 23:40
@DoubleAA The issue in B'rachos 51a is whether to recite the b'racha rishona after finishing to eat, thus possibly "eating more garlic" with a b'racha l'vatala (at least according to Rashi's reading of the gemara). Accordingly, it sounds like the parallel you're suggesting in the OP might be that he should not make a b'racha acharona as it would somehow be l'vatala. That's not what you meant, is it? Is there a reading that it refers to blessing before eating more, in which case more garlic would refer to not making a b'racha? Or did you mean the more general reference in Shabbos 31b?– FredSep 3, 2013 at 0:34
If I have some cake, eat a bit and forget to make a b'racha, but want to go on eating cake, I certainly should make a b'racha rishona now on the remaining cake as I have not yet made a b'racha that covers it.– CashCowJul 7, 2016 at 15:04
Yes, he makes one. Source: The Halachos of Brochos, by Rabbi Yisroel Pinchos Bodner, (self-published, distributed by Feldheim, 1989, second printing, March 1990), chapter 15, section C.2, citing Magen Avraham 172:2 and Mishna B'rura :3. (The Machatzis Hashekel there notes that this is obvious.)
