Would you like to add a Blue Thingy recipe?
The quickest, easiest way to do them is to buy a big bottle of Tarantula pre-mixed blue Margaritas, toss it in the blender with a little extra premium tequila, a squeeze of lime and some ice and blend it. Then pour it into a nice big, chilled, salted glass. Normally, I don't care much for premixed drinks, but these are exceptional. Gotta br sure it's Tarantula though. Salvador's makes one, also, and it is nasty! A friend of mine brought a bottle of that over one night about 6 or 8 months ago and at least half of it is still sitting in the fridge.
To make from scratch, it's basically the same as a regular Margarita, only with blue curacao instead of Triple Sec.
