The Tommy's Margarita cocktail was created by Julio Bermejo in the 1980s. Julio is the son of Tommy Bermejo who founded in 1965 with his wife Elmy the restaurant "Tommy's Mexican Restaurant" in San Francisco, an establishment specializing in tequila that offers nearly 300 varieties. The recipe for Tommy's Margarita is now one of the IBA's modern classic cocktails.
The cocktail is considered a variant of the famous Margarita cocktail which is a true symbol in Mexico, the original triple sec is replaced here by agave syrup. Agave syrup is also called "agave nectar" and it has the consistency of honey. Do not look for it in the syrup department, but rather in the honey, dietary or organic department, if not in a store specializing in this type of product.
