I grew up eating burnt rice on the bottom of a pot of cooked rice. Not no more though.
The texture and flavor of the burnt is like charbroil and the crunchy is like popcorn chips. It was delicious but I also learned and still subjective is that the burnt anything is carbon and if you eat burnt particles or carbon, you may get cancer.
Plus eating anything hard will have an effect on your stomach and linings cuz that's hard stuff that your internals will have to digest. Some disease take years to develop so yeah. Just wanna make that point.
Plus my viet people are big with sharing food like hot pot. Now everyone be licking their chopsticks and dipping into the same bowl of hot pot and so everyone may share the same disease. Nevermore.
