A lot of people these days like them frothed up (with egg white/aquafaba etc on top of the pineapple) and served in a coupe a la clover club. I am ambivalent about this, I think it's frothy enough with the pineapple. It's always fun to get a nice head on any drink though.
The drink itself is a bit sweet for me, lemon juice tempers it quite well if you like that sort of thing .
it's nice to have a creative use for Chambord
I used store bought pineapple juice which was quite sweet (no added sugar though) and it masked the vodka more than most flavored martinis. That can be good since some do not like the vodka taste. I liked the Chambord in it.
