Yeah, I get that. The frustrating part is trying to explain suet to the butcher. Most have never even heard of it, or what it's used for, or how to get it. And the ones who do know what it is seem to want to talk me out of using it. It's just so weird.
"Suet? What's that?"
"Do you mean lard?"
"Do you mean tallow?"
"Do you mean birdseed?"
"What are you cooking with it?"
"Oh right, one sec." (leaves, returns with a brick of lard) "Here ya go!"
I must have had that conversation a half-dozen times yesterday. But I was finally able to get it from a butcher (an actual butcher, at a meat market--not a supermarket or grocery store), who actually knew what I was talking about. "Oh sure, we usually stock that for Christmas. Looks like the shipment will be in on Monday, you're lookin' at about $2/pound."
