Q. (See question 2135). When the flavor of the maror is very strong, how long should one chew the maror in one’s mouth before swallowing, taking into account the strong stinging sensation involved?
A. Since one does not comply with the mitzva of maror, if it is just swallowed, Horav Shlomo Miller’s opinion is that by just chewing it a bit, one complies.
Hwever, care should be taken not to eat maror that is so strong that it is practically unfit to be eaten.
Other Poskim maintain that in such case one can mix it with other types of maror. (See Hilchos Pesach 29: 2).
