All -
Well, we pulled out the Duck prosciutto yesterday and knifed into it to see how we did. Overall the coloring looks perfect and firmness appears to be correct (although we have never done this before). The issue I am concerned about is after cutting into the breast we noticed slight moisture on the the pieces as we cut them. Is this normal?
We cured for about 10 days in my ground level closet. The temperature ranged from 48-66 degrees. Humidity was mostly in the high 40s but dipped into the high 30s once or twice and then into the 50s and 60s. Definately not your ideal curing chamber, but it seemed to have worked. We will be upgrading with a humidifier the next time.
Here is a picture of it (can't see moisture, sorry, iphone picture):

Overall it tasted good and everyone woke up today. Hardly Duck flavored though.
Got the two breasts from Fox and Obel and unfortunately they were 8oz a piece (instead of the 16oz one that the book calls for).
Drizzled with some fresh Tuscan olive oil (delivered from the vineyard about 15 days ago) and a whack of fresh ground pepper and it made for a delightful tasting (this was our break from our bacon tasting - details to come on that).
