Interruptions between the Beracha and eating

From Halachipedia

Speaking as an interruption

  1. The Gemara Brachot (40a) mentions the opinion of Rav that one who says to another to take of the bread before he has a chance to eat himself may still eat without having to make a new Beracha. The same is true for one who tells another to get the salt or dip.
  2. Tosfot comment that nowadays people eat their bread without salt. The implication is that asking someone to bring salt after making the beracha would then constitute an interruption, or hefsek, and one may then need a new beracha to eat. Only speech that relates to the piece of bread itself would not be a hefsek. [1]

  1. By that logic, the salt isn't required for the bread itself. Such appears to be the opinion of the Rashba (Shut HaRashba 1:208) where one was fine having the bread plain. In that way, asking for salt is like ordinary speech, which constitutes a hefsek.
