The success of this recipe is dependent on temperature (use vodka from the freezer and cordial from the fridge), your choice of lime cordial [It works...
We love this. While, to our taste, the recipe is really well balanced, we couldn't resist adding six drops of grapefruit bitters, just to wake it up a bit. btw the review mentions Vodka but we did it with Gin as per the recipe. We might try it with Vodka next time...maybe no dilution needed that way...we'll see.
