Chapter 56 – Benedictions Pronounced Erroneously
56.1) Some benedictions pronounced erroneously over bread or cake are okay, as-is. An erroneous benediction over cooked food or grapes may need correction.
56.2) Benedictions pronounced in error over fruit may have to be rectified (See source for details, or consult a rabbi.)
56.3) If you say the wrong benediction over wine and do not immediately correct the error, do not do anything about the error.
56.4) If you say Shehakol (blessing for animal products: meat, chicken, fish, and eggs; water and all other drinks (except for wine) and soups; and miscellaneous foods like mushrooms, candy, etc.) over an article of food, your duty is fulfilled.
56.5) If you mistake one food for another, or one drink for another and say that benediction, you have fulfilled your duty even though you realize your mistake after the fact.
56.6) If you say the wrong benediction and then correct it in the middle, that is okay also.
56.7) If you say the entire wrong benediction and realize it immediately, you should say the correct one before proceeding.
