Having just returned from five weeks in France (working, but it pays the bills...) I have got the taste for the filet mignon fumé (amongst other Lyonaisse delights) which was sold in the nearet market (with the encouragement of the very pretty girl who insisted on my trying a bit every time I passed her stall).
So, there's some on the go now. Having consulted the interwibbly, the usual approach seems to be to salt (no cure) for a period of between 4 hours and 4 days, rinse, coat with pepper and hang to dry. The recipes are all a bit vague about target weight loss and all of those things that we worry about.
The story so far: I salted a nice pork fillet (with a very small amount of sugar) for 20 hours (being the geometric mean of 4 hours and 4 days!) and then rinsed. The weight loss is now 17% and it's stiff as a stiff thing. Coated it with ground mixed peppercorns and mixed herbs, and it's now in the smoker along with a nice piece of salmon. I shall give it one run of the CSG, then hang in the curing cabinet, then give it another smoke next week when some bacon should be ready for a run.
So, it's relying on salt, water loss and smoke to keep it safe. I'll be aiming for a weight loss of around 35%. Does that sound reasonable?
