A gift for Yom Kipour

Hi! Non Jewish person talking here,

I’m going to spend two days at my aunt’s house next week. It will happen during Kippour and her husband is Jewish, they are going to celebrate and I know that the fruit Cedrat, is kind of really important for the holy day and I’m currently in a region where they produce some. So I have 2 questions:

1) As a non Jewish, is it a good gift to bring a cedrat for my family?

2) Cedrat is a kind of sensitive fruit, do you have advises for transportation/conservation ? (I’m going to take a plane and two train and I’ll buy it one week before kippour)

Bonus question (does Cedrat liquor or jam, or any other preparation with cedrat make a good gift?)

Thank’s for your time!
