- Bring to a boil, then turn down the heat and simmer for 20-25 minutes.
- Taste, and adjust seasonings.
- Add sherry and simmer 5-10 more minutes.
- Mix cornstarch with water until smooth.
- Add a little bit at a time until desired thickness
- (should be quite thick, the sour cream will thin it down).
