How to be Mafrish Challah

Beigel's Medium Braided Challah 30 Oz. - Pack of 2 Challahs

According to Harav Y.S. Elyashiv zt"l, (Ashrei Haish Y.D.)

The proper way to do Hafroshas Challah is to have in mind,

when removing the Challah from the dough  not to be yotzie 

the Mitzvah.

After making the Bracha holding the Challah in the hand, 

you raise the Challah and have in mind with this to perform the 

Mitzvah of Hafroshas Challah.

1)The Challah should be held in your hand while making  the Bracha.

2) The Bracha should be done before the performance of the Mitzvah.
