Saying the correct blessing – Research and study:

The sages established six different blessings for six different groups of foods.

1. The blessing of Hamotzi is to be recited over bread as will be explained in length in chapter ??.
2. The blessing of Mezonos is to be recited over five grain products, as will be explained in length in chapter ??.
3. The blessing of Hagafen is to be recited over beverages that derive from grapes, as will be explained in length in chapter ??.
4. The blessing of Haeitz is to be recited over fruits of the tree, as will be explained in length in chapter ??.
5. The blessing of Hadama is to be recited over vegetables and fruits of the ground, as will be explained in length in chapter ??.
6. The blessing of Shehakol is to be recited over all other food products, as will be explained in length in chapter ??.

Requirement to say correct blessing:^[1] One is required to recite the correct blessing that has been designated for each and every food. If one is not knowledgeable in the laws of blessings and as to what blessing should be said over which product then he is required to visit a Sage to study the laws of blessings [or purchase a Sefer or go online and research the correct blessings].

Saying Shehakol instead of correct blessing:^[2] Accordingly, even though the blessing of Shehakol covers all foods as will be explained in Halacha 16??, this is only Bedieved, however initially it is forbidden for one to fulfill his obligation with the blessing of Shehakol and rather one must research and study what blessing is to be said for the corresponding food.
