 A Lemon Drop is typically prepared straight up , meaning that it is shaken or stirred with ice , strained , and served in a stemmed glass , such as a martini glass . The glass may be prepared with a sugared rim , performed by dipping the rim of the glass in water or lemon juice and then dipping it into a rimmer ( a shallow tray used in bartending ) , filled with sugar . Superfine sugar ( also called " bar sugar " , " caster sugar " , " castor sugar " and " ultrafine sugar " ) , which is more finely ground compared to standard granulated sugar , is sometimes used for this purpose .
