The Sáicar (according to our Cassell’s Spanish-English Dictionary, that’s Spanish for “sidecar,” although actual Spaniards have told me that the dictionary’s talking through its hat) incestuously splits the difference between the Margarita and the Sidecar and is none the worse for it.

1 lemon wedge
Large-grained sugar (such as “Sugar in the Raw”)
Kosher or margarita salt
1 1/4 ounces Spanish brandy
1 ounce reposado tequila made from 100 percent agave
1 ounce Cointreau
1/2 ounce lime juice
1/2 ounce lemon juice

Before chilling your cocktail glass, moisten its outside rim to a depth of 1/2 inch with the lemon wedge and then roll the rim in a mixture of two parts sugar to one part salt. Shake the brandy, tequila, Cointreau, and citrus juices and strain into the chilled glass.
