Q. What would be the brocho in the case above when the bread or matza was mixed and cooked in deep oil?
A. Horav Shlomo Miller’s Shlit’a opinion is that if the mix was fried in deep oil the brocho would become Mezonos.
See Vessen Brocho (p. 469, n. 25) that quotes a similar opinion from Horav S.Z. Auerbach and Horav Eliashiv ZT”L, when the bread or matza pieces are less than a kezais.
