I usually take my whiskey straight (or with some sweet vermouth

), but I recently came upon some pisco. It's probably not the highest quality stuff ever, but I'm not up to drinking it straight (tastes like bad grappa, and I do enjoy a good grappa). Both my mother in law and recent episodes of The Mole have suggested pisco sours, so why not?
Except, the orange/yellow tinted high fructose corn syrup makes everything gross. What brand do you like (that I can get in the northeast), or what's your favorite recipe?
