Made a huge pile of lo mein for dinner last night. It was really good, but was missing something that I just can't put my finger on. There's some taste that the lo mein from the restaurant has that I wasn't able to replicate last night. Some...umami.
Here is a rough lineup of my ingredients, in no particular order:
What is the missing taste? It's definitely a sauce component, not a veggie or meat. The shrimp and char siu were just perfect. Is it MSG?
What is it that makes that wonderful taste?
