Rim the edge of a margarita glass (or glass of your choice) with a meyer lemon. Pour some course salt on a small plate and roll the edge of the glass in the salt. Set aside.
In a shaker, combine the tequila, pomegranate liqueur, meyer lemon simple syrup, meyer lemon juice, and lime juice with some ice cubes. Shake for 10-15 seconds, then strain into margarita glass over some ice cubes. Garnish with pomegranate seeds and meyer lemon slices.
Meyer Lemon Simple Syrup
In a small saucepan, combine the sugar, water, meyer lemon juice and lemon zest. Bring to a boil, then strain into a glass bowl. Set aside and use when cooled.
