Lemon Macaron Recipe

• Prepare 2 parchment paper lined baking sheets. They need to be big enough to hold 30 x 1 ½/4cm diameter shells each.
• Mix the ground almonds and powdered sugar (and cocoa powder, if using) together in a bowl, then grind in a food processor until you have an extra fine texture. You may need to do this in batches, depending on the size of your food processor.
• Sift into a large bowl (I use a mesh strainer and push the mixture through with a spatula), putting any bigger pieces of almond back into the food processor to re-grind.
• Add half of the egg whites and mix thoroughly into the almond mixture. At this point, you can add food colouring or flavouring such as vanilla seeds, citrus zest, essence, if desired. ( I coloured mine yellow) Set aside.
• In another bowl, or the bowl of a stand mixer, scrupulously clean and free of any oil or egg yolk, beat the remaining half of the egg whites to stiff peaks.
• Meanwhile, put the granulated sugar and water into a small heavy-based saucepan and heat on medium-low to 244°F/ 118°C, without stirring.
• While whisking constantly on low speed (to avoid splashing hot syrup), slowly add the cooked sugar mixture to the beaten egg whites, pouring it down the inside edge of the bowl. You’ll get a bit of it hardening on the side of the bowl, but that’s okay – just leave it there.
• Whisk at high speed until the mixture is cool, about 3 minutes. About 1 minute before the end, you can add food colouring, if not done at the almond paste stage. The mixture should increase in volume and become firm and shiny, and it should be thick and marshmallowy when you lift the whisk.
• Scrape the meringue onto the almond mixture and incorporate with a rubber or silicone spatula. You do actually want to get a lot of the air out of the mixture – you do this by folding and squashing the mixture against the side of the bowl, rotating the bowl a quarter turn with each fold. Be sure to firmly scrape the bottom of the bowl with the spatula, so you don’t leave a layer of almond paste there.
• Mix until you have a homogeneous batter that runs from the spatula in a thick ribbon.
• Transfer the mixture into a piping bag fitted with a #10 – #12/7 – 9mm plain round tip (this is best done in two batches, so you don’t overfill the bag). Pipe 60 equally sized rounds, about 1 ½ inch/4cm in diameter, in staggered rows onto the prepared sheets. Hold the piping bag upright with the tip just above the sheet and pipe without pulling upwards or swirling in circles, so the batter comes out in a round blob around the tip, and give a little sideways flick at the end to break the stream.
• Tap the baking sheet firmly on the bench several times to release air bubbles and obtain a smooth surface. If you have any tips sticking up, press them gently down with a damp fingertip.
• Leave the tray to rest at room temperature for at least 20 minutes until a slight skin forms. If you touch it, it should be only just tacky.
• Meanwhile, preheat oven to 300°F/150ºC.
• Bake the macarons in the centre of the oven for 18 minutes one sheet at a time, turning the sheet half-way.
• Remove from oven and remove the parchment from the tray with the shells still on it and place on a cooling racks for at least 30 minutes, until completely cool, then remove macaron shells carefully from the parchment.
• If not filling straight away, store in an airtight container at room temperature, separating layers with parchment. Otherwise, fill and store in an airtight container in the fridge to mature for at least 24 hours before eating.

Filling

• Place chopped white chocolate in a small bowl.
• Place the cream in a small saucepan and and heat cream until just before boiling point. You should see steam rising from the surface and a few bubbles starting around the edges.
• Pour hot cream over the white chocolate and allow to stand for 2 minutes,
• Stir to thoroughly combine cream and chocolate.
• Add lemon oil or extract.
• Taste and check if it is lemony enough for your tastes.
• Refrigerate for 30 minutes or until thick enough to pipe or spoon onto macaron shells.
