How does one make Havdalah on this Motzei Shabbos / Tisha Be’Av if you have to eat.
If one needs to eat, havdallah is made in the normal fashion (hagafen, followed by the havdallah blessing).
Havdallah should not necessarily be made immediately on Motza’ei Shabbos, but only before one needs to eat, whether it is day or night.
Grape juice should be used, rather than wine.
For more details, please see this week’s article, which will be sent out later today.
