This pattern can also be found in the book Yummi 'Gurumi: Over 60 Gourmet Crochet Treats to Make by Christian Haden. I've borrowed the book from my local library, and being a beginner, the patterns are quite challenging, since they often require more than your good old amigurumi single crochet, but there are definitely some impressive creations there. My favourite is probably the pork bun, since it looks so real.
