I normally steer clear of commercial London Dry Gins. The other day my wife brought home a bottle of Tanqueray Rangpur Gin because the supply of my homemade Gin was depleted (geez! wonder how that happened?). I had a sip of Rangpur and was blown away! The citrus profile is beyond delicious. The label hints that the rangpur lime is rare. It is actually not.
The rangpur is a natural cross between a female citron fruit and a male mandarin fruit. In fact, our citrus type fruits all can trace their origins back to the citron fruit.
The rangpur lime grows in south east Asia and even in the USA. The rangpur lime is called canton lemon in China; hime lemon in Japan; limao galego in Brazil; and mandarin lime in the USA.
If you are a craft distiller or even a home distiller, try to source some of these limes. The Gin you create will be truly elegant!
