Step 1

Trim off the very ends of the lime, then cut the lime lengthwise into quarters.

Step 2

Rub one of the lime quarters around the rims of two glasses, then dip the rims in salt to coat.

Step 3

Add the lime quarters, tequila, water, sugar, and orange liqueur, to a blender. Blend on high speed until the lime is broken down and only small specks of green remain, 1–2 minutes. Strain the mixture through a fine-mesh sieve into a spouted measuring cup to remove any solids, pressing to extract as much liquid as possible.

Step 4

Fill the glasses with ice, then evenly divide the margarita mixture between the two. Garnish each glass with a lime wheel and serve immediately.

Step 5

Enjoy!
