After having moved to the UK, where Vietnamese food is not so readily available in areas outside of London (and similar) I’ve gotten used to making my own pho.
The main problem are the herbs as it can be hard to get all the necessary herbs outside of Asian supermarkets.
It’s a really good dish for special events as well, since few people I’ve met dislike pho.
I would say that a lot of the cooking process is hard to explain via a book. Videos are good. This one seems to be done by a very knowledgeable woman. https://youtu.be/xxM4t8vP-0A
After skimming the above video I’m really impressed by that woman’s knowledge. One thing i am not sure she discusses is the process of skimming the fat off the broth.
