Notes
While this is particularly a bucatini pasta recipe, this pasta sauce can easily go with various other pasta of choice options.Thick spaghetti (not thin, the cream is too heavy), fettucini, pappardelle, or Tagliatelle all make fine solutions.Due to the nature of the sauce, you may need a little more or a little less sauce to pasta ratio to balance the noodle.
