In most modern jesa, the feast is offered to the ancestors through a ceremony involving different family members placing dishes of food on the table and pouring rice wine into cups, as gracious hosts would do for their guests.
After the food and drink is set out in a specific order, the family members leave the room to give the spirits time to enjoy it.
After a few minutes, the eldest male relative clears his throat to signal to the spirits that they are going to come back in, and the family then takes the food into a separate room and all eat and drink the offerings together, connecting them with the deceased after having paid them respect.
