Tonight I made 3 margaritas, drinking small amounts of each.
Each was made with a half lime squeezed, about half-ounce triple sec, 2 ounces tequila. Well stirred, no ice. After tasting each, I added a dash of Grand Marnier to each, which was a slight improvement.
The first used a blend of tequilas I made which incorporates a South African tequila-like drink. This did not work well, due I think to that South African drink which has a very earthy flavor I find hard to like.
The second used only 4 Copas Blanco. This was better, but the big vegetal flavor of tequila rang through and I am not used to it (I almost never drink tequila).
The third one used only Herradura Reposado. This I liked the best. The tequila flavor was evident but seemed more refined, tamed. There were no earthy green pepper notes or rather they were much more subtle than in the other versions. With the Grand Marnier (just a light dash) this was an excellent drink and I am finishing that one.
