=D. First off, no you don't have to put the spicy sauce on, it's personal preference. A lot of people just put a bit of sesame oil (참기름/cham-gi-rum) and it's super savory.
Second, that's an EXCELLENT idea for a future post. All the side dishes together are called 밑반찬/meet-ban-chan and the culture/variety behind them are definitely a mystery to most. I'll do a post on them in the near future!
post about it and used sesame oil but just for the post - prefer it less oily really.@hansikhouse I actually don't put sesame oil on my Bibimbap ny hubby hated the smell - I did - make one
