Behind the Bar: 31TEN's Signature Margarita Recipe

A great margarita is rarely about the recipe card. It is about feel — the weight of a shaker, the bright pop of cold-pressed lime, the way a salted rim catches the light on a Santa Monica evening. At 31TEN Lounge, the signature margarita has earned its place the slow way, through late nights of tweaking ratios until every sip landed exactly right.

We wrote this guide for anyone who has stood at a home bar wondering why their margarita tastes flat, sour, or worse, syrupy. The fix is rarely expensive equipment or rare bottles. It is the same lesson we share with regulars walking in from Main Street. Pull up a stool, or read on from your place in Bondi, Byron Bay or Fitzroy, because the technique travels well.

Australians know how to drink in warm weather. Whether you are set up on a balcony in Brisbane as the sun dips over the Story Bridge, or sitting outside a small bar in a Melbourne laneway in February, the appeal of a tart, well-built cocktail is universal. Our version pulls together tequila, fresh lime, a touch of agave, and one quiet ingredient most home bartenders forget.

The Tequila Foundation

The single biggest decision you will make is the tequila. Skip the mixto bottles and reach for a 100 percent agave expression. A blanco gives the cleanest, brightest profile and lets the citrus sing. If you want a softer, slightly earthy character, reach for a reposado rested in oak for a few months.

Australian spirit lovers are spoilt for choice. Distilleries from the Adelaide Hills to the Mornington Peninsula are putting out agave-based spirits that hold their own, and local bottle shops carry a deep range. A good rule of thumb: if the bottle lists agave azul on the label and shows no added sugar, you are on safe ground. Pour two ounces per serve — that is the foundation.

We use a blanco at 31TEN because it gives the cocktail its clean, almost glassy texture. Mezcal enthusiasts occasionally ask whether we swap in smoke, and the honest answer is no, not in the signature pour. Smoke changes the conversation, and our recipe is about clarity of flavour.

The Lime Factor

Fresh lime juice is non-negotiable. The bottled stuff carries a metallic edge no shaking hides. Plan on about an ounce of juice per cocktail, roughly one fat lime per serve. Roll the lime firmly on the bench before cutting to break the internal membranes and yield more juice.

Citrus season in the Southern Hemisphere peaks between June and September, so if you are batching for a long arvo on the patio in January, source Australian-grown limes from markets like Queen Victoria Market or your local greengrocer. The Tahitian variety you find year-round works beautifully here, with a slightly floral edge that plays nicely against the tequila.

Strain out the pulp and seeds through a fine mesh. You want a clean liquid, not a pulpy soup. Cocktail purists will tell you to juice to order, and they are right — but if you are batching for mates, you can hold lime juice in the fridge for up to 24 hours before the aromatics begin to fade.

Sweetness and the Orange Liqueur

A margarita lives in the tension between sour and sweet. Too much sugar and the drink becomes a candy-coloured slushie. Too little and the lime bullies everything else off the plate. We use a small pour of quality orange liqueur, around half an ounce, plus a bar spoon of light agave nectar to round the edges.

Cointreau remains our house pick. It carries real bitter-orange peel and adds body without syrupy weight. Triple sec works in a pinch, though the cheaper versions lean toward confectionery. If you are pouring at home and want to stretch your dollar, look at Australian-owned producers like Mr Black or Maidenii who offer equally balanced alternatives for other builds.

For the agave, raw blue agave syrup from a health food aisle is fine. Skip the dark, caramelised version — it pushes the drink toward molasses territory. Stir the agave into the lime juice before you add the other liquids, so it dissolves properly in the cold mix.

Shaking and Chilling Properly

Build the drink in a shaker filled with ice. Add the tequila, orange liqueur, lime juice and agave, then shake hard for twelve to fifteen seconds. You want the shaker to frost on the outside — that cold burn is how you know the drink has reached proper dilution and chill.

Hard shaking also aerates the cocktail, which gives the finished pour that cloudy bloom you see in a properly made margarita. A Boston shaker with two tins is the professional tool, but a sturdy cobbler shaker with a built-in strainer works just as well at home. If you are making several at once, build each one individually — the timing matters more than people think.

Strain off the ice and pour into a fresh glass. Never serve a shaken cocktail over the same ice you shook it with, as it has already given up too much water. The drink should arrive bright, cold and slightly frothy on top.

Salt Rims and Presentation

For the rim, run a lime wedge around half the outer edge of a rocks glass, then dip lightly into flaky sea salt. We use a coarse Australian sea salt from the Eyre Peninsula at the lounge because the crystals catch light beautifully, but Maldon or any flaky variety will do. Only rim half the glass — it lets the drinker choose their salt hit with each sip.

Strain the cocktail into the prepared glass over a single large ice cube, or serve up in a chilled coupe if you prefer a sharper, colder pour. Garnish with a thin lime wheel, or a small sprig of coriander if you like a herbaceous lift. For a sense of how we present the drink at the lounge, browse our gallery.

Presentation is more than window dressing. The visual weight of the glass, the salt against the rim, the colour of the drink under lounge lighting — these small touches change how the cocktail tastes in your mouth, a phenomenon bartenders in Sydney or Perth small bars will confirm.

Pairing the Pour with the Plate

A margarita is a versatile partner at the table. The acidity cuts through rich, fatty foods beautifully, which is why it has become a quiet favourite alongside tacos, ceviche and grilled seafood on our food menu. The salt rim acts as a seasoning, priming your palate for whatever arrives next.

If you are batching at home for a long lunch, build a jug using the same 2:1:0.5 ratio of tequila to lime to orange liqueur, with the agave adjusted to taste. Pour over a large ice block and let guests serve themselves — a relaxed approach that fits the Australian way of entertaining.

If you enjoy experimenting with classic builds and want to take another technique home, our piece on the art of crafting a classic Old Fashioned at home walks through a slower, stirred serve that rewards patience in much the same way.
