I spent many years in SE Asia. A dish called Sur Longhai (thai dish) translated to 'Crying Tiger' . Grilled beef with a very spicy but tasty dipping sauce.
I remember telling people in the late 80s onwards about Thai food and Sriracha sauce which originates from the town of Sriracha on Eastern seaboard. Nobody was interested. I predicted Thai cuisine would become popular in UK. Again nobody was interested. These days. Thai spicy seafood soups, Green and Red curries are all over the place, and people rave about it. Funny old thing.
Sriracha sauce is nice with mayo, as has been mentioned above by my old mate Splott P. However, if you add a bit of soy sauce or asian seasoning sauce in with it, it is great as a dip for steamed mussels.
