Take some of the blood, and hit it on the two side posts and on the upper door post of the houses where they’ll eat it.
This is what my mom remembers from when she was young. When she went to see her Bene Israel friends in Virjoli, a village south of Mumbai, she saw them slaughtering a goat for Passover. They then marked their doors and windows with palms dipped in the blood. Mom’s maternal grandparents lived in Virjoli, which is also known as Samba. They had a lot of land and two homes there, so it was a very big village.
