From East and West:
How does a Sephardi act when praying in an Ashkenaz minyan?
What are the main differences between Sephardim and Ashkenazim in the
laws of Shabbat, Avelut, and Kashrut?
What does a Sephardi do when he is eating at the home of an Ashkenazi
and is served sweet challah?
What are the halachot and things to know about when Ashkenazim and
Sephardim get married to each other?
Can an Ashkenazi be served kitniyot when he is staying at the house of
a Sephardi for Pesach?
Can a person from Eretz Yisrael do melachah in chutz laAretz on Yom Tov sheni?

These are just a sample of all of the practical questions that are
dealt with in this book. FROM EAST and WEST (previously published as
Mi’Mizrach Umi’Maarav) covers a vast spectrum of halachot. This book
deals with all of the primary halachic differences between Sephardim
and Ashkenazim, how a Sephardi has to act when he is in an Ashkenaz
community, minyan, or yeshivah, and the applications of the
prohibition of Lo titgodedu (making separate factions).
This book is primarily meant for Sephardim and follows the rulings of
Maran Chacham Ovadia Yosef zt”l, but it also provides source material
for Ashkenazim.
