Fanfic research

Hello!! I sincerely apologize for this post as I understand it may come across as brazen or rude. That is not my intention. I’m researching food and customs for my fanfic series, in which a character is Jewish canonically. I strive for authenticity for these characters, and want to represent people accurately. I’m not Jewish myself, but I have a really rough understanding of Judaism, but my fear is that it is so rough, I may harm one my readers accidentally. So I wanna learn! I’m actively researching on my own independently, but I know research can only take me so far. I wanted to know what you guys enjoy and do culturally. I wanna know how to represent these traditions and values with as much care as I can give. I really appreciate any answers I get in advance. Thank you!!
