The Mexico is one of the 15 Tequila based drinks in the Café Royal Cocktail Book, published in 1937. I have written the recipe as it appears in the book, which happens to be in parts, rather than ounces or ml.

1/3 Fresh Lime or Lemon Juice

Teaspoonful Syrup

2/3 Tequila

Shake

I found this drink to be out of balance, but if your a fan of very sour, then this could very well be your thing.

Give it a try and share your thoughts….
