(Special guest presentation by HaRav Shemuel Pinhasi of Jerusalem, translated and explained by Rabbi Mansour)
It is universally accepted among the Poskim that when a person recites a Beracha before eating, the Beracha is effective only with respect to the foods that the person had in mind while reciting the Beracha. If he decides he wants to eat a different food, which he was not thinking about at the time of the Beracha, he must recite a new Beracha.
It is less clear, however, whether this applies to a Beracha Aharona. Meaning, if a person ate two foods that require the same Beracha Aharona, and as he recites the Beracha Aharona he has in mind only one of them, must he repeat the Beracha Aharona to cover the food about which he was not thinking when he recited the first Beracha?
This issue is subject to debate among the Halachic authorities. From the comments of the Ben Ish Hai (Rav Yosef Haim of Baghdad, 1833-1909), in his work Rav Pe’alim, it appears that in his view, a Beracha Aharona differs from a Beracha Rishona in this respect. Unlike a Beracha Rishona, a Beracha Aharona covers all foods, even those which the person did not have in mind as he recited the Beracha.
A practical example of this Halacha is a case of a person who ate a food requiring Al Ha’mihya – like cake – and also dates. After eating dates one is required to recite the Beracha of Al Ha’etz, but the Gemara in Masechet Berachot rules that if one mistakenly recited Al Ha’mihya over dates, he fulfilled his obligation. Since dates are nourishing, and thus bear a certain resemblance to grain products, they are covered by the Beracha Aharona of Al Ha’mihya (though of course, optimally one should recite the proper Beracha of Al Ha’etz). Rav Eliezer Romm, a prominent Rabbinic figure in 20th-century Jerusalem, was asked about a case of a person who ate dates and cake, and then recited Al Ha’mihya over the cake but forget to recite Al Ha’etz over the dates. Has he fulfilled his obligation through the Beracha of Al Ha’mihya that he recited, or must he recite a new Beracha to cover the dates?
Rav Romm answered that the individual must recite Al Ha’etz, and did not fulfill his obligation through the Beracha of Al Ha’mihya that he recited.
A number of scholars found this response difficult to understand, as it appears to contradict the Gemara’s explicit ruling that the recitation of Al Ha’mihya fulfills the obligation of Beracha Aharona for dates. This question was posed to Rav Tzvi Pesach Frank (1873-1961), the Chief Rabbi of Jerusalem, who explained Rav Romm’s ruling. He claimed that although one who mistakenly recited Al Ha’mihya over dates fulfills his obligation, this applies only if he intended for the Beracha to cover the dates. In the case under discussion, however, the individual recited Al Ha’mihya thinking only about the cake, and therefore it cannot cover the dates.
Of course, this ruling presumes that a Beracha Aharona is effective only with regard to foods that a person has in mind as he recites the Beracha. As we saw, however, this was not the position of the Ben Ish Hai. In his view, a Beracha Aharona covers even foods that a person did not have in mind while reciting the Beracha, and therefore, in the case described, one would not recite another Beracha, since the Al Ha’mihya which he recited covered both the cake and the dates, even though he had in mind only the cake. This is, indeed, the ruling of Hacham Ovadia Yosef.
Summary: When one recites a Beracha before eating food, the Beracha is effective only with respect to foods which he had in mind when he recited the Beracha. A Beracha Aharona, however, covers even foods that a person was not thinking about at the time of the Beracha. Therefore, if a person ate two foods which require the same Beracha Aharona, but had only one of the foods in mind when he recited the Beracha Aharona, he fulfilled his obligation and does not have to repeat the Beracha.
