Maror
Place some of the dry charoses into the wine in the plate beneath your becher. Take a kezayis of maror and dip part of it into the charoses, and then shake it off. Recite the berachah of Al Achilas Maror, having in mind that the berachah also applies to the chazeres, and eat the maror without leaning.
The shiur of a kezayis of maror is ¾ oz, including both the lettuce and the horseradish. It should be eaten within a kedei achilas pras.
Korech
Take a kezayis of matzah from the bottom matzah and a kezayis of maror from the chazares. Put some dry charoses on the maror and then shake it off. Recite Kein asah Hillel and eat the korech while leaning to the left.
The shiur of a kezayis of matzah for korech (which is miderabanan) is ¾ oz. If there are eight matzos to a pound, this equals 3/8 of a matzah. The shiur of maror for korech is the same as its shiur for maror, ¾ oz. Both together should be eaten within a kedei achilas pras.
