I added the recipe link and notes to the post as an edit.
If anything, it’s consistency was a little thicker than many chowders. Between the roux, the cheese, and the many small bits in the soup, it is very thick. I liked it this way, but I could see using more broth to thin it out a bit.
The soup is heavy. I am a big guy who can easily put back a few bowls of soup at dinner. I could barely finish two half-full bowls.
