The daiquiri’s trans­for­ma­tion from a clas­sic shaker cock­tail ordered by griz­zled men to a Slurpee favored by soci­ety girls began with the inven­tion of the elec­tric blender. Shortly after its intro­duc­tion at a 1937 restau­rant show in Chicago, the War­ing blender (finan­cially backed by the band­leader Fred War­ing of Fred War­ing and the Penn­syl­va­ni­ans) rev­o­lu­tion­ized bar drinks. As early as 1939 the cock­tail writer Charles Baker was refer­ring to the “new style” of blender daiquiri. (“We do not even know Mr. War­ing, but we like his music and his Blender,” Baker wrote.)Excerpted from: Wayne Cur­tis, “The Old Man and the Daiquiri,” The Atlantic Monthly, Octo­ber 2005, p. 133
