Can sour cream be subbed for the heavy cream in both these recipes?
The sour cream could work as a replacement in the soup. However, the heavy cream provides the only fat in these biscuits. As such, they will not be as tender if you use a low fat ingredient such as sour cream.-JonDebbie, full-fat sour cream should yield an acceptable result in the biscuits. However, I believe it would curdle if you reduced it down with the vermouth to use as the soup base; it would also potentially give the soup a rather weird tangy flavor, I suspect, so I don't recommend it.
