HI Nezoat- Thanks for bringing this to our attention. Generally speaking, we publish recipes to our site exactly as they appear in the book from which they were taken. Pasta spellings do vary from book to book, which can make things a little confusing. Marcella Hazan (and my Italian/English dictionary) spell the word 'fettuccine' but many other variations exist, including the one 'c' variation you mention. Sorry for any confusion, but happy to hear you found the recipe you were after. Enjoy the pasta- however you spell it!
All the best,
