Gin and Tonic Macarons

The other day, probably late in the evening on my commute home when I was wishing it was summer, I was thinking about gin and tonic icing/frosting again. I was thinking about how although tasty, my previous incarnation was low on tonic flavour because you need quite a lot to get a strong enough flavour but too much liquid makes the buttercream curdle. And then an idea hit me, what about using tonic concentrate, like the Soda Stream stuff?  So a plan was hatched and successfully carried out. And here it is the recipe for Italian Meringue Gin and Tonic buttercream filled macarons!


For the shells see my last post and use some green food colouring in the mix! Leave them to cool completely before filling.


For the filling:

Basic Buttercream Recipe (makes enough for 4 lots of macarons but freezes really well)

  • 375g white caster sugar
  • 1 tbsp golden syrup
  • 100ml water
  • 6 egg whites
  • 500g soften unsalted butter in 2cm-ish chunks

For gin and tonic buttercream – this is the amount of flavour for 1/4 of the buttercream above

  • Zest of 2 limes
  • Juice of two limes
  • 1 tsp of Soda Stream gin and tonic concentrate (you can buy it in Ocado and most big supermarkets)
  • 3 tbsp nice gin (I used Sipsmith’s this time)


  1. Put sugar, golden syrup and water in a medium heavy bottomed saucepan and stir until totally combined.  Brush the inside of the saucepan with clean water on a damp pastry brush to dislodge any stray grains. Set over high heat and bring to a rapid boil. When the sugar mixture has come to the boil add a sugar thermometer and keep cooking until it reaches will into soft ball stage, 121°C
  2. Meanwhile put the carefully separated egg whites in the bowl of an electric mixer (with a whisk attachment) and whisk the egg whites to soft peaks – be careful not to over whisk. Then slowly pour a steady stream of sugar syrup into the egg whites, being careful not to hit the whisk while doing so – I find pouring down the side of the bowl is the easiest way of doing this. Continue whisking until sides of the bowl feel cool. Add the softened butter chunk at a time one by one at a time and whip until fully incorporated and smooth
  3. Take 3/4 of the mixture out of the bowl (I freeze it in 1/4 mix portions and then defrost in the fridge overnight and re-whip when I need them – if the mix curdles when you do this just keep going, it will eventually come together) Add the flavourings and mix until incorporated
  4. Pipe it into the macaron shells and sandwich together
