Americans drink a lot of Margaritas. While the Margarita makes up eighteen percent of the mixed drinks ordered in the United States, tequila represents only six percent of the domestic spirits market. Unfortunately, we drink a lot of bad Margaritas too. Neon colored, super-sweet, artificially flavored, poorly made, cheap ingredient, frozen-slushy Margaritas surely account for most of those eighteen percent.
Perhaps one reason that Americans drink a lot of bad Margaritas is that we seem to have no idea of its origin. There are theories (among others) that Dallas socialites, Peggy Lee, Mexican (or Irish, or Texan) bartenders, German ambassador’s daughters or Ziegfeld Follies dancers all have a hand in the drink.
Used 1.5 oz of ice cream and the more generous 1/4 oz of demerara syrup
Would recommend a preliminary shake/strain with ice or chilling all the ingredients beforehand as the ice cream really doesn't chill things down. A quick pulse blending also helps to make a more homogeneous drink .
Overall the lime/cream mix works really well with brandy! Swapping the proportions for rum/brandy also probably would be really good as well
