I have some really nice, locally rendered lard in the freezer and was planning to use some for a savory crust. The last time I made pate brisee with this lard, I used half cultured unsalted butter, and half fresh lard. It was delicious.
Am tempted to try all lard, although a few folks have warned me it'll be a lumpier, heavier crust, although I can't imagine why.
I use Ruhlman's 3-2-1 Ratio recipe for my crusts.
