Yummmm. Only substitution was yogurt for the whipping cream (to cut abit of fat). By accident I added more lemon juice (used Tbsp vs tsp) but ended up enjoying it.
Oh my gosh, this was absolutely fantastic! Used good dry sherry, Parmigiano-reggiano cheese, and the optional capers. Served with fettucine, pan-roasted broccoli, and garlic bread. Thanks for sharing the recipe!
