2 tbsp tequila
3 tbsp orange liqueur or triple sec
150g/5½oz icing sugar
500ml/17fl oz double cream
1.Pour the lime juice, tequila and orange liqueur or triple sec into a bowl and stir in the icing sugar until it dissolves.
2.Add the cream and whisk until the mixture is thick and smooth, but not stiff.
3.Spoon into an airtight container and place into the freezer to freeze overnight. This ice cream doesn't need to be taken out to soften before serving, as it won't freeze too hard and melts quickly.
4. Grate a little lemon rind on top and serve in small cocktail glasses
