Margarita recipe from a real pirate

A guest gave me the real recipe for Margarita, the Margarita drunk by pirates. 1 ounce is 28,47 grams

3 parts of Tequila (40 grams)

2 parts of Triple sec (25 grams)

1 part of fresh lime juice (15 grams)

all shaken and served in a cold glass

serve with a 1/4 of fresh lime in case the pirate wishes to squeeze it

ok to use lime-juice (Roses) in case fresh lime is not available
