I have the mesh bags they used when cooking the broth
but Ive never been able to make a good pho
cant get that broth taste right
I start with a good beef stock. I roast off all the bones and veggies till they got that nice brown char on them. Not burnt. Once I get the stock going I let it go for a good two days. Making sure to skim the fat off the top every hour or so. I keep the flame almost as low as it will go but not all the way. I put the side of the pot over flame. Not in the center of the pot. This makes the fat go to the side that is not over the flame and makes it easier to skim.
Once the stock is made i strain it through a chinois into a clean pot. I take some of the bones from the stock and place in there as well. I also add the beef chuck chunks at this point(make sure to boil before adding to stock - this will help keep the stock from getting cloudy. Bring it to a boil and add the charred ginger, onion, about 3 tablespoons of sugar, and fish sauce. Start slow with the fish sauce and go until it gets the desidered taste. Lower down heat and simmer on low for about an hour and a half. Add the star anise and cloves to the water for at least a half hour. Add a tablespoon of sea salt. At this point the broth should done and should have that desired flavor.
Side note: Pull the beef chuck chunks when they have reached desired tenderness and run under tap water to let cool down and slice at that point. Usually this is about the 40 minute mark.
If you need the rest on how to prepare i can go into more detail, but I just wanted to give you an idea on how to get that broth.
The key to vietnamese cooking is highlighting the beef flavor. I try to keep it as simple as possible.
