Blueberry, Lime & Fleur de Sel Macaron Shells

?37g water

powdered purple food colouring or Wilton gel paste

55g egg whites (old egg whites aged 12-24 hours in a bowl on the kitchen bench)

STEP 1. MAKE THE TPT

Mix the Tant Pour Tant (equal quantities of icing sugar and almond meal) with the fresh egg white until it forms a thick paste, cover with cling wrap and set aside.

STEP 2. MAKE THE IM

Pour your aged egg whites into a Kitchen Aid mixer and insert the whisk attachment.

Bring the caster sugar, water and food colouring to the boil in a small saucepan.  

When the sugar syrup reaches 115°C start whisking your aged egg whites into soft peaks.  

As soon as the syrup reaches 118°C slowly pour the syrup into the beaten egg whites in a thin stream. Continue whisking the IM in the Kitchen Aid until it reaches a temperature between 50-55°C. 

STEP 3. COMBINE THE TPT & IM

Gently fold in the rest of the IM into the TPT and combine until you have the right texture (should be glossy and look like cake mixture).  Be careful not to over-mix the batter here or it will get too runny and your shells may crack in the oven.

STEP 4. PIPE YOUR MACARON SHELLS

Fill a piping bag with the macaron batter and place some parchment paper over a baking sheet.   

Put four small dabs of macaron mix underneath the parchment paper in each corner to secure the paper.  Pipe 3.5 - 4cm diameter circles onto the parchment paper, tap the tray on the work surface to remove air bubbles and leave to dry for about 15-20 minutes to form a crust and are dry to touch.

STEP 5. COOK YOUR MACARON SHELLS

Cook the macaron for 17 mins at 150°C (fan forced oven).  To release steam, leave the oven door open slightly.  If this doesn't work for you, keep experimenting until you find the right temperature as every oven is different.  Once cooked, remove from the baking sheet and leave to cool on the parchment paper over a wire rack.  I have a new commercial style oven which is very powerful so I have to reduce the temperature by another 20°C and cook my shells for 19 minutes. 

STEP 6. ASSEMBLE YOUR MACARON

Remove the shells from the parchment paper and pair like sizes together. Pipe a decent blob of ganache onto the shell, then place the lid on top and twist slightly so that the ganache flows out towards the edge of the macaron. When piping the ganache onto the shell always leave a small rim.

STEP 7.  STORE YOUR MACARON

Store your macaron in the fridge for 24 hours prior to eating so that the humidity helps the ganache to soak into the shell and allow the flavours to develop.  Try not to eat your macaron the day they are made as they are too dry.  Allow the macaron to return to room temperature prior to serving.  The recipe for the Blueberry, Lime & Fleur de Sel Ganache appears in my previous post.
