I was making a chicken Galantine from Ruhlmann's Charcuiterie, and it calls for 8 oz of pork back fat. I had some in my freezer that's probably been there for 6 months, sealed in the airtight pouch it came in. As soon as I cut it open, it didn't really smell great, it smells like that not so fresh smell from an asian grocery store.
I don't remember back fat smelling like that. Is it bad or is my nose more sensitive today?
