Just wanted to put this out there - I have been looking for caul fat to make the country pate from the Les Halles cookbook. Stuart at Central Market Westgate told me that they have to order it in 10 lb frozen blocks, and since demand is low, they don't do it regularly. BUT, he did it for me, it came in today, and will be thawed and portioned for sale by Friday. I'm down for a lb, and thought some enterprising Austin hounds might be interested in grabbing some.
Here is a CH thread on uses for caul fat: http://chowhound.chow.com/topics/277835
