Funny how summer leads to ice cold refreshing cocktails.
You will need, GOOD olives, a hot BBQ and a skewer or two.
This takes a bit of timing, but make up a very very cold version of your favourite martini.
Thread your required number of olives onto a skewer & BBQ. First they'll sweat, then they'll begin to char at this point take them off the heat. Drop the hot Olives into the cold martini they should split, dirtying up your martini nicely.
There you go one dirty martini.
(I mean it about good olives, thats why I'm using Kalamatas)
