I thought they had it on DVD, possibly sold separately? On iTunes it's available!
Never heard of masserini but I have a never fail-couldn't be easier recipe that I can suggest:
200gr of ricotta (fresh cheese, can't be replaced am afraid)
200 gr icing sugar
200gr coconut flour (desiccated)
Just mix together, if you want you can split the mixture in two and add some cocoa powder to one half. Roll into small balls, bite-sized, and roll onto more coconut so that you dust them well (takes 5'!). If you have any mini-muffin paper-case you can put them in. Refrigerate until serving. Yummy. Perfect for summer when switching the oven on is an unbearable thought. (Clearly, that's a once in 7 years situation in the uk, but nevertheless, they are good :-)
