Boiling Beef Chorizo as part of a soup base?
Ive tried this a few times.  I think boiling the chorizo can be beneficial for some soups because it allows the flavor to penetrate the other components.  However, boiling it also makes the meat pretty indistiguishable and mostly just imparts flavors to the soup (in my case ive used mexican chorizo).  Maybe another thing to think about would be the oil content which could allow you to craft a flavorful rue.  rue is made from simering equal amounts of oil and flour on low heat (timing wise less is more) and will thicken your soup.
