Korean cookbook that I really like. I make her kimchi stew recipe once or twice a month. She has a YouTube channel and is just so pleasant.
I don't have a cookbook to recommend, since I only use family recipes, but try some Jewish recipes. I think a lot of people don't think about Jewish food when looking at different cultures. You can never go wrong with matzo ball soup.
I'm shocked no one has mentioned Maangchi's big book. She has a blog and a YouTube channel, but this book is where it's at. I prefer it over koreatown. https://www.amazon.com/dp/1328988120/ref=cm_sw_r_apan_glt_fabc_46ZFTRG9SFEQ26D7JKZE
I'd also add Bravetart, and Japanese home cooking. Dessert person is also phenomenal.
Maangchi. Has online videos and two cookbooks
