Bracha Rishona
From Halachipedia
Minimum Amount
- There is no minimum amount necessary for Bracha Rishona, even if one eats a very small amount of food one must make the appropriate Bracha. [1]
When is a new Bracha Rishona required?
- As long as one didn’t have a hesech hadaat (interruption of thought) one doesn’t need to make a new Bracha Rishona. However, if one made a Bracha Achrona, and one wants to eat again a new Bracha Rishona is needed. [2]
