Valentine's Day cocktail names tend to be as corny as the cards and due to strawberries being uncannily heart-shaped, many Valentine's cocktails have strawberries...
How about going all out for Valentine's Day this year, and offering your sweetie a dozen roses? That is to say a dozen cocktails with "Rose" in the name. Not all at once, of course, but what could be more romantic than stretching Valentine's Day out to two weeks, with a one day buffer and one day to recover, i.e., a dozen roses? Make him or her or they a new cocktail every day for 12 days! And consider my own "Rose Darling" among them!
