A. Hamotzi – Said Hamotzi instead of correct blessing:

Correct blessing is Mezonos – Pas Haba Bekisnin:^[1] If one accidentally recited the blessing of Hamotzi on a baked Mezonos food which is defined as Pas Haba Bekisnin, then one fulfills his obligation and the blessing of Mezonos is not to be recited.^[2] This applies even if one did not set a meal over the Pas Haba Bekisnin food. Upon finishing eating, one recites the regular after blessing of Al Hamichyeh and not Birchas Hamazon, unless he ate enough to require Birchas Hamazon.

Correct blessing is Mezonos – Tavshil of Hei Minei Dagan:[3] If one accidentally recited the blessing of Hamotzi on a Mezonos food which can never become Hamotzi [i.e. cooked pasta, deep fried Sufganiyot donuts, cholent with grains, oatmeal porridge, etc], then one does not fulfill his obligation and must repeat the correct blessing of Mezonos on the food.^[4]

Correct blessing is Hagafen, Haeitz, Ha’adma, Shehakol:[5] If one accidentally recited the blessing of Hamotzi on Hagafen wine or grape juice, or on a Haeitz fruit or Ha’adma vegetable, or on a Shehakol product, then one does not fulfill his obligation and must repeat the correct blessing of Hagafen, or Haeitz, or Ha’adama, or Shehakol.^[6] This applies even to legume bread which is Shehakol or Mezonos [i.e. rice], nevertheless, one does not fulfill his obligation and he must repeat the correct blessing.[7]

Other Opinions: Some Poskim rule that the blessing of Hamotzi never covers Mezonos, even by Pas Haba Bekisnin, and hence the blessing of Mezonos is still required to be recited. The proof is from the fact that regarding those breads which are disputed whether they are Hamotzi or Mezonos it is ruled that Mezonos is to be recited. This implies that if one were to recite Hamotzi then he would not fulfill his obligation according to the opinion which requires Mezonos to be said. [Elya Raba 168:20; Igros Moshe O.C. 2:54 unlike Igros Moshe Y.D. 3:120 -2]

[2] The reason: As these foods contain the same form as does bread and thus it does not appear that one is lying when saying the blessing. [Chayeh Adam ibid]

[4] The reason: As it appears like a clear lie to say “Hamotzi” over this food when in truth it has no resemblance of bread. [Chayeh Adam ibid]
