I had an urge for oxtail pho, so I looked up a couple recipes to find the seasons to use for the broth. Taking that and a few things I had tried before for beef pho, I played with it and tweaked it until I ended up with a rich, hearty broth full of spice and season.
From what I understand, there’s thin light pho which is more of a light broth and there’s heavy bold pho. The second one is the one I favor, and although technically a clear soup, it’s darker and the flavors are more in your face.
First, I started a broiling an onion, some pork bones and oxtails until they were partially cooked and I had brought out the flavor and oils. Then pork bones and oxtail went into a large pot of water, simmering there for a few hours. When the oxtail was cooked but not yet falling off the bones, I pulled them and immediately put them into an ice bath, then stored the in the refrigerator once cooled.
