If there any trimmings from one cake at my house I put them on a plate one the kitchen counter and like a miracle they disappear without any trace within minutes.
It seems that there are never too many trimmings for me to worry about being wasted.
Larding is, was mostly used for large cuts of beef.( And old cows ) Also any game like venison, elk moose , bear and wild boar. I did hear that it was also needed for horse meat but I have never seen horse being served in a restaurant
