But I have finally learned the secret for getting a good margarita in Europe. Oh yes I did!
First Step: Ask the bartender if they have Rose's Lime Juice.
If they say "yes," ask them to replace the lemon juice with Rose's Lime Juice. Voila! Mission accomplished. Sit back and sip with a smile on your face.
If they say "no," give up.
If you insist on ordering one anyway, get a side order of Sprite and use it to "doctor" the margarita and make it drinkable.
Two further notes...
- If you like it "on the rocks," just ask for it to be served over ice cubes. European bartenders do not uniformly understand the phrase "on the rocks," regardless of what language is used.
- Think before asking for salt on the rim. They generally just use regular table salt, which really doesn't have the same effect as the rock salt normally used. Might be better to just skip that part.
