Mix up a refreshing A Really Good Non-Alcoholic Margarita for a bright, spicy sip without the buzz.
Warm the sugar and water together briefly with a generous handful of cilantro and a few chunks of jalapeño so the sweetness picks up bright herbal and spicy notes. Bring the mixture just to a low simmer for about five minutes, watching for the sugar to fully dissolve and for the liquid to take on a faint green tint and a fragrant aroma. Once infused, strain the mixture through a fine sieve into a clean glass jar so the syrup is clear and glossy; discard or reserve the solids for composting. Chill the sealed jar in the fridge for easy assembly later.
On a small shallow ceramic plate, gently combine coarse salt, a little sugar, and Tajín until the grains are evenly speckled—this will be the textured rim that gives a sweet‑salty‑chile contrast. Lay out halved and quartered limes, a small bunch of cilantro with leaves and stems intact, and a sliced jalapeño in a separate bowl for garnish. Keep a small glass jar of the cooled jalapeño‑cilantro syrup and a pitcher of tonic water nearby so everything is ready when you assemble the drinks. Brush a lime wedge or a touch of syrup on the glass rim to make the Tajín stick when you serve.

Layer a few clear ice cubes into a short rocks glass, rimmed with the Tajín mixture, then pour in 1.5 ounces of fresh lime juice and 2 ounces of the chilled jalapeño‑cilantro simple syrup. Top gently with tonic water to taste and give a careful swish to combine; the drink should read pale greenish‑yellow, slightly viscous around the ice, with tiny effervescent bubbles rising through it. Garnish with a thin jalapeño slice tucked on the ice, a small sprig of cilantro, and a lime wedge perched on the rim. Enjoy immediately—bright, spicy, and balanced.
