It is a wonderful glass from which to quaff powerful margaritas. It’s pretty hefty, so it stays cold for quite a while. I don’t remember where it came from, though. Sorry.
Speaking of which, you may be interested in my margarita recipe. I’ve changed it since then, though. I now use half a fresh-squoze lime (you can see the squeezer in the background) and agave nectar instead of the margarita mix.
It snot warm at all today.
