Oh Yeh !! I'm liking this one !!

I'm using a personal favorite gin: Four Pillars Bloody Shiraz. And Punt e Mes instead of the noted vermouth (which I do not have).

This cocktail is now on my "make again and again" list !!
.

YO !!! This is Fantastic !!! Rich, Big, Strong, Full Flavored !! My particular palate really really likes this one !!

And if I may ..... I just found this Merry Widow(er) ......
