What bracha do you make on 1. Melba toast and 2. bagel chips (sold in snack bags)?
Commercially produced bagel chips are made directly into hard small cracker like chips and are mezonos. Melba toast is made as bread and then toasted. In factories it is made with intent to immediately turn it into cracker like toast. The bracha for this is questionable and ideally it should be eaten only after washing on real bread.
Home made bagel chips and melba toast made from leftover bread is hamotzi.
