How to control the heat (serrano vs jalapeno)

Serrano brings brighter, hotter heat than jalapeno, which is what gives this spicy margarita its kick. For a milder drink, swap in jalapeno, remove the seeds and white ribs, or muddle fewer slices. For more fire, leave the seeds in or add an extra round. Balance any heat with a touch more simple syrup or lime.

Salt rim, Tajin, or naked

A classic salt rim tempers the spice and adds savory contrast. For extra flavor, use a chili-lime salt or Tajin rim. Rim only half the glass if you want the choice sip to sip. Wet the rim with a lime wedge, then press it into the salt.

Best tequila and juice

A crisp blanco (silver) tequila keeps this bright and lets the serrano lead; a reposado adds a rounder, oaky note. Always use fresh lime juice, since bottled tastes flat against the fresh pepper.

Make a spicy margarita pitcher

Scale the tequila, lime, simple syrup, and orange liqueur by six in a pitcher, add sliced serrano to infuse to taste, and strain before serving so it does not get too hot. Rim the glasses ahead and pour over fresh ice.
