I've never read or seen anyone use cardamom in lure making, it surprises me a bit. Cardamom is warm, spicy, and sweet, with complex notes of citrus, mint and eucalyptus, plus earthy, woody, and balsamic undertones, creating an invigorating, aromatic, and slightly camphorous aroma. Does anyone know why cardamom is so little used/described in lure making?

Have you used it? I have to be honest I am not familiar with it. The description you gave makes me think it would be great in a sausage recipe. I can't imagine it would not get some response in a bait of some sort.

There are many things that are not written or shared with regards to use of different ingredients in formulation. That is like sharing one of your productive hunting, trapping or fishing areas with another. A smart man never shares such things. A dumb man pays the price.

I’m so old I remember “ Macys doesn’t tell Gimbels”.

Yes its been good for me, I grind cardamom pods and mix it with castor, have great succes in marten lures.
