...Gin next time. After tasting everything in the shaker tin before adding ice I realized I could omit the sugar syrup. The Boston is a great use for Apricot liqueur. It stars & shows that it can be a frontrunner in the flavor profile, if not sharing the lead , along with Gin.
I just got a bottle of Rothman & Winter Apricot liqueur, and am searching for cocktails to use it where the flavor comes through distinctly. I've made a Stone fruit sour which was very nice and the Charlie Chaplin, once with lime and the other a Right Charlie with lemon. Tonight I made this cocktail and changed the ratios a bit thinking it was a little sweet for me. I used 1.5oz Fords gin, a scant 1oz R&W Apricot liqueur, 3/4oz lemon juice & a bar spoon liber and co. Grenadine. I'll add more...
Try a Silk Road .. it's only 10ml from the 90ml total, but my notes: 'Rich apricot jam given a dark twist from the bitters, and a charred orange slice (we had no grapefruit). Very nice, definitely worth more than 4*'
It's a household favourite, and in the core rotation.
