Some oldsters (like me) on this Board have been discussing topics like authenticity online for over 20 years.
I think I understand where you are coming from. Once you are at my old stage of life, you might see where I am coming from. Or you might not.
This type of topic where posters debate whether a food being served in Toronto, with different ingredients, imported ingredients, different terroir, people of another ethnic or cultural background preparing a dish, Thai by Thai chefs and not by Chinese, Mexican or Sri Lankan chefs, etc. becomes a repetitive and boring topic after it’s been discussed a dozen or 10 dozen times.
One of the BEST Thai restaurants in Toronto, is no longer is in business, because Torontonians were too cheap for the restaurant to stay afloat, since higher quality ingredients cost more money. This was before the rapid inflation of the past 3 years, that restaurant had an excellent Mexican chef, and the restaurant was owned by immigrants from Hong Kong. Maybe Toronto will eventually be ready to spend $75 per person on an excellent Thai meal, the way they are willing to spend money on French food, some upscale Japanese, some upscale Italian Italian restaurants. Ultimately, the people who live in or visit Toronto are the ones who determine which restaurants stay in business. Many restaurants alter their recipes , menus, service approach, to serve the Toronto market, to survive in a fickle business with tight margins that are getting tighter.
You are getting some thoughts from people who are Gen X (like me), Boomers, and Silent Gen (born before 1945).
Feel free to write your thoughts down about what you hope to find, and share what you like or find uninspired.
The beauty of Chowhound and HungryOnion is that they were and are Discussion Boards, where people share thoughts and perspectives.
The thing about Taste, is that there is no Accounting for it.
Who is the Arbiter of Authenticity?
Borders change, ingredients change, recipes change, what is considered authentic changes.
Opinions about taste and authenticity, and whether authenticity in Toronto matters, will vary depending on the poster’s outlook and experiences.
These topics are inherently subjective. I know which posters are on my wavelength, and which posters have interests which are different than mine.
Enjoy your food journey.
