Corn on the cob is a great ingredient to add as it's very cheap, adds flavour to the soup, and if at the end of the meal you're still hungry that will surely fill you up.
The pork luncheon meat is actually something I had from a Korean hotpot years ago (and yes, I googled it, your spelling is spot on 👍. Since then it's been a staple ingredient in my hotpot
Will definitely try the corn next time. I don't know how flavorful it will be, so I'm very curious.
I tried adding sausage on time on the hotpot, because I also saw it in the Korean hotpot, but the boyfriend didn't like it so not sure if he would like the pork luncheon meat too. But if it's just me eating, I'll definitely add it. 😂
