Based on your post...the key selling point of your book is, YOU. Not the recipes. If it was the recipes - you might not be wondering how to get traction. Why do I say this? As a lover of international/traditional cooking...if there's a book out there, even 1...on a cuisine with low coverage - i'm on it like a fly on shit. I'll just scan the recipes quickly, and if it looks legit....i'll snag pretty much straight away.
Reading the blurb for your book does nothing for me. I need to know who you are...I need to like and invest in you.
As much as it pains me to say it - because i'm not a user of these technologies, absolutely abhor them and think they're evil - but the way books like this get in hands of people - are through viral marketing channels like Shit-tok, instagram, TV foodn networks and so on. The first question i have when looking at your book blurb is "who is Bruno?"
I think you need to work on the YOU part, then the cookbook part afterwords for this to work like you expected :)
