The first image is Sriracha sauce, it's a sauce originating from Si Racha city, hence the name, unfortunately the city is very unpopular as it's overshadowed by nearby Pattaya only 30 minutes away, but the sauce has spread worldwide through the rooster brand

Granted, I'm not from Si Racha, though I used to live in Pattaya and visit there often.

The second image is Udon noodles, and this is an example of a food that accidentally shares a name with another thing, in this case there is a city in Northeast Thailand named Udon Thani, but once again the city is really niche and not well known at all

The pronunciations of Udon (noodles) and Udon (city) are completely different, but I thought it was a noteworthy example
