Smoked cuts were quite a controversy some ...years.... ago, people saying they were too OP.
Then smokers were changed from being dirt cheap to requiring steel and iirc also higher skills, turning a nice thing for newer players into an exclusive tool for more advanced players making alts.
And then smoked cuts were nerfed in their stats.
And they were far not as OP as fruits are now.
So that is why they may seem disappointing to you now.
Asides from that, I kind of like the idea, if it'd be restricted to the less popular recipes, otherwise it may buff some high end foods too much.
From the implementation side, it should not be too hard to make a new group of "any meat cut" (to include smoked cuts) besides the already existing "any raw meat cut",
and smoked cuts, given their own multipliers, should blend in without much work either, so this might be very easy to do, which is why I like it.
