Honestly? Ramen. There are way too many ingredients that all needs to be cooked differently, and even the broth itself is a nightmare amount of effort for what you get at the end.
I spent 2 days cooking my first ramen broth, the tare, the marinated eggs and the garlic oil. It's definitely a case of tripling the batch and freeze it because it takes a lot of work regardless of the quantity.
I don't know if there is anything special about Ramen broth, but once you get used to the process, homemade bone broth is absolutely worth it.
I get pork knee joints from the Asian market, bake them at about 400 for an hour, and simmer on the stove top for a couple of days. That broth is my winter staple.
I'd say a lot of my favorite Asian dishes follow this pattern. Most of them are pretty challenging to recreate due to the amount of ingredients and types of cooking involved. Guess there's a reason they taste so good
I made homemade General Tso's and it is absolutely worth the effort. The recipe I used stayed crispy for days even with sauce on it. I could control the flavor. It was so good.
You can kind of use a simplified method to get a good broth with a pressure cooker, because from what I read, the key to getting something good seems to be a sustained hard boil with lots of collagen and fat on the meat.
