I have been wanting to try this pasta for quite a while now and finally got up the nerve to try and make some. I think it came out very well. Originally, the sauce does not include any vegetables or protein. I changed that and used some large dice zucchini, shrimp, scallops and quartered crimini mushrooms. I like those additional items as it gives the pasta a good texture and mouth feel. Vodka Sauce is a popular Italian-American pasta sauce known for its rich and creamy texture. The exact origins of vodka sauce are unclear. One popular belief is that vodka sauce originated in Italian-American restaurants in the United States during the mid-20th century, more than likely in the 1970’s. Vodka was added to tomato sauce as a way to enhance the flavors of the ingredients. Vodka is thought to interact with the fat in the cream and the acid in the tomatoes, creating a smooth and balanced sauce. Here is a link to the recipe. Enjoy. https://www.rockinrs.com/CS-Penne-Pasta.pdf
