Put all the ingredients except the lime wedge in a blender and blitz until smooth. Tip into a cocktail, margarita or rocks glass, garnish and serve.
Blood orange margaritaWhen blood oranges are in season – or you can get blood orange juice in a carton – make this with 50ml tequila, 25ml lime juice, 25ml blood orange juice, 15ml sugar syrup and 25ml blood orange triple sec: Cointreau Blood Orange and Solerno from Sicily are both great. If you like bitter-sweet drinks, you could add a dash of Campari to it, too.
Lemon sorbet margaritaSimply make your margarita as usual but before you blitz it in the blender, add a scoop of your favourite lemon sorbet (depending on how sweet it is, you might want to add a bit of sugar syrup too), then blend away. This would also work nicely with raspberry, grapefruit or orange sorbet.
Watermelon margaritaIt’s always nice to have a bag full of deseeded watermelon chunks in the freezer so you can knock up a watermelon margarita at a moment’s notice. Just throw in a handful straight from the freezer and then blitz away. Give it a taste and adjust the sweetness if needed with a bit more sugar syrup.
