My first instinct was to think about Italian food in general. Vodka threw me off briefly—was this about drinks? But Carbonara made it clear we're talking about pasta dishes.
Then I started testing: Vodka sauce—yes, that's a creamy pink tomato sauce with vodka. Carbonara—the famous Roman egg and bacon sauce. Pesto—the Genovese basil sauce. Alfredo—butter and cream. Marinara—simple tomato sauce.
The beautiful thing about this puzzle is how it spans different sauce bases. Tomato-based sauces (Vodka, Marinara), cream-based (Alfredo, Carbonara), and oil-based (Pesto). Different colors, different textures, but all pasta sauces.
