The beautiful thing about this quick and easy pasta dish recipe is that it succeeds in tasting both rich and light. How is that possible? The sauce is made with a combination of creamy mascarpone cheese and a lively amount of lemon. The richness comes from the mascarpone cheese and the citrus brings a brightness to the dish, so it's not too heavy. Marscapone cheese can be found in the dairy or cheese section of any better grocery store.
