Don't sell the book, sell your story. People buy stories & how those make them feel as a person, they do not just buy the product.

I have marketed books in the past and they are generally very difficult to sell because discovery is challenging. Cookbook category is especially very competitive and AI tools have made everything worse. So your best bet is to promote your story on social media and try to generate word of mouth. You could try spending some money on Amazon on keywords which are extremely tightly related to your cook book stuff and check if it generates any value, try with a small amount.
