The merciless virgin is a tiki classic, invented at the long-closed skipper kents bar and restaurant in san francisco. The establishment and the man himself may be gone, but skipper kents legacy lives on through recipes like this one, which we found in the smugglers cove recipe book. The smugglers cove version is adapted from a recipe found in skipper kents unpublished manuscripts, accompanied by a quote from the rubiyt of omar khayym: she must be merciless. Ah Moon of my delight that knows no wane the moon of heaven has risen once again. For a tiki drink, the merciless virgin is surprisingly bright and crisp, thanks to the healthy measure of lemon juice and a topping of sparkling water. The curaao should be dry if possible (like a pierre ferrand, rather than a grand marnier), and a caribbean shrubb is better still. You can get away with shaking this small measure of sparkling water in a shaker, but if you double up the recipe you may wish to leave the sparkling water out and pour it over the drinks at the end. If youre short on club soda or seltzer, plain or even flavored sparkling water (like lemon or cherry) are fine.
