Prepare the glass: Start by rimming your margarita glass with salt or sugar. To do this, rub a lime wedge around the rim of the glass, then dip it into a plate of salt or sugar. Set aside.

Blend the peaches: In a blender, add the peach slices and blend until smooth. If you prefer a chunkier texture, you can mash them with a fork instead.

Combine ingredients: In a cocktail shaker, add the peach puree, tequila, triple sec, lime juice, and simple syrup. Add a handful of ice cubes and shake well for about 20 seconds.

Serve: Fill your rimmed margarita glass with ice. Strain the mixture from the shaker into the glass.

Garnish and enjoy: Garnish your drink with a peach slice and a lime wedge on the rim. Serve immediately and enjoy your delicious Peach Margarita!
