Q. I take bread and put it into a blender and leave it on until it is as fine as it'll get, not exactly like flour, but close to it.
If I mix this "dust" into a salad, do I make a HaMotzi or Mezonos?
If I mix the "dust" with eggs and/or with onions, and fry it, do I make a HaMotzi or Mezonos?
A. Since there are no pieces of bread that are the size of a kezais and whatever there is does not have the looks of bread, hamotzi will not be recited. However in regards to mezonos other factors should be considered.
On question 1493 in regards to the brocho for french fries that contain a small amount of flour (5%) for taste, we wrote; Shulchan Aruch (O.H. 208: 2,3) rules that due to the importance of the basic five grain products, any food which is made of flour from one of these grains is mezonos and the brocho achrona is al hamichya. The above applies even if there is a majority of other ingredients, as long as the purpose of adding flour is to fill one up, give a taste to the food, or make the food more fit for consumption. However, the above is only true when the taste of the flour is recognizable. (Mishna Berura 208: 49 and Biur Halocho).
Letorah Vehoroah (5: 21) rules that for fish cutlets fried with bread crumbs or matza meal, the brocho is shehakol. Vessen Brocho (p. 78) quotes contemporary Poskim who maintain that if the batter is thick, the brocho is mezonos.
Horav Shlomo Miller’s Shlit’a opinion is that french fries that contain only a small amount of flour the brocho should be haadomoh, since the flour taste is used to subdue the flavor of the fries. The Rov pointed to Avnei Nezer (1: 38) for a similar ruling when the flower is used for binding.
Likewise in our case. If the flour dust does not provide a satisfying fulfilling sensation, the brocho should be haadomo or haetz for the salad, or shehakol for the eggs.
