One of my favourite cocktails / one of the only ones I can make. Its a pretty standard recipe apart from it actually fills a big margarita glass. This is high in alchol, but I assume thats what you're looking for so it's fine. Enjoy!
50ml Triple Sec
25ml Sugar syrup
75ml Lime juice (about 1 lime)
Handful of ice cubes
Salt for the rim
Coat the rim of your glass in lime juice and then dip into a salt covered plate.
Add all your ingredients to the blender and just whiz it up until you have a nice alcoholic slushie
Pour into your glass and enjoy!
