Make a Tequila Mockingbird II!

2 ounces Reposado tequila
1 ounce limoncello
1 ounce lemon juice
1/2 ounce simple syrup
2 dashes Angostura bitters
1 twist of lemon

Combine all liquid ingredients in a shaker filled with ice. Shake vigorously and strain into a chilled cocktail glass. Garnish with a twist of lemon.

Tends toward the sweet side but an amusing way to use up limoncello until summer time. You may prefer less (or no) simple syrup, especially if the limoncello is already on the sweet side.

Another favorite limoncello recipe but this is more of a summer cocktail:

My Favorite Mechanic is a Woman
1 bourbon
1 limoncello
1 lemon juice
1 Canton ginger
1 egg white

Dry shake then shake with ice and strain into Collins glass over fresh ice. Cherry garnish.

Hmm, not quite summer time but maybe a drink for the sampler?
