I enjoy a good Fruit Tingle, but the recipe that's typically used in Australia (where it's imbibed most) is actually with grenadine syrup rather than a raspberry liqueur. I've also seen it served with a raspberry fruit cordial instead.
I found this drink to be rather sweet personally, so after following the recipe I decided to make it again, which I used 60ml Vodka instead of using 45ml and used 15ml of Blue Curacao instead of using 30ml, which the drink turned out to still be sweet but not as overpowering, making it more enjoyable to me personally
