This recipe doubles easily. You could add other fruit to make it more festive. If the orange and lemon slices are left in too long their rinds add bitterness which can be unpleasant. Some people like to add soda water to give a bit of fizz. Adjust the recipe to suit - more of less syrup, fruit, juice. Some people also add brandy for added complexity. America's Test Kitchen only uses 60g sugar, but I prefer it sweeter. Leftovers can be frozen as ice blocks on sticks for an adult treat.
100g sugar - 8 tablespoons
100 mls water
1.5 litres Merlot, or other fruity red wine
120 mls triple sec or Cointreau
Heat sugar and water together until sugar is dissolved. This is called Simple Syrup.
Slice 2 oranges thinly, and juice the other.
Slice both lemons thinly.
Combine all ingredients in a pitcher and chill at least 2 hours for the flavours to meld.
Serve in chilled wine glasses half filled with ice.
