Limoncello was an intriguing concept for me, typically made from the zest of tart lemons that have little bitterness. Lemon zest, or peels without the pith, are steeped in a base spirit until the oil is released. The resulting yellow liquid is then mixed with simple syrup (Wikipedia link).
The result fruity citrus liqueur with a lower alcohol level, that is consumed chilled, straight, after dinner in some parts of the world.
My son gave me a bottle of Pallini Limoncello. Upon opening, I got the immediate scent of Lemonheads candy! I poured a sample into a shot glass and took a sip. It was sweet, and the taste of lemon candy persisted. I was not tart as I was expecting. As is the case for me, even the lower amount of alcohol wiped out my taste buds.
While I do not drink it straight, I have used it in cocktails in place of lemon juice or sour mix, to interesting effect.
