Midsummer happy hour! This one comes from fooling around with Dixie Peach juice cocktail from Trader Joe's, though any similar peach concoction would probably work. Less is more, as it turns out. (Name courtesy of my wife, who makes puns in many languages and is lovely to boot.)
3 parts gin
3 parts peach juice cocktail
1 part Triple Sec
1 part Rose's Sweetened Lime Juice
Shake with ice until very cold (it's a bit on the sweet side—you could also cut down on the Triple Sec, although I didn't like that as much) and strain into the aquarium of your choice.
Imbibe to the strains of the first stonefruit-themed piece of music I thought of off the top of my head, Frank Zappa's "Peaches en Regalia." Here's the great sage, equal of heaven himself, in Vienna in 1988.
And, just to hit both sides of the pun, the eponymous variations from the famous Perlman-Zuckerman-DuPre-Mehta-Barenboim performance of Schubert's "Trout" Quintet.
