The claremont is served at the hotel of the same name, a stately old manse in californias bay area. Its based on the newfangled, muddled-fruit style of old-fashioned-esque cocktails, and uses dry curaao (pierre ferrand, specifically) in place of the usual simple syrup. You can use a sweeter style of curaao, like grand marnier, but you may wish to pull back on the measure a bit unless you have a sweet tooth. A caribbean orange shrubb isnt half bad here, either.
