These macarons were delicious. The salted caramel had just the perfect balance of sweetness and saltiness. I had three people tell me that they weren’t fans of caramel but that they would happily eat these again. What an endorsement! I think the shell could have been slightly firmer, but the salted caramel buttercream was clearly the hero. NOTE: based on Pierre Herme’s Macarons (note Pierre Herme uses a lot of couture ingredients, which I haven’t repeated below)
7.5gcoffee extract(instant coffee can be used as a substitute)
7.5gyellow food coloring
For the Italian Meringue
150 gcaster sugar
167gpouring cream
180gsalted butter(of which 142.5g should be softened at room temperature)
Instructions
Process the almonds and icing sugar in a food processor until it is fine. Stir together the coffee extract, food colouring and first portion of the egg whites and then pour into the processed almonds and icing sugar, but do not stir.To make the Italian meringue, bring the water and sugar to boil to 118 degrees. When it reaches anywhere between 110 to 115 degrees, whisk the second portion of egg whites to soft peaks on a medium speed. You’ll need to time this correctly so that when the sugar reaches 118 degrees, it is ready to be poured over the egg whites. Be careful not to pour the syrup on the whisk. Continue whisking on medium speed and then increase the whisk to high speed for the last few seconds. Fold the meringue into the sugar almond mixture. Spoon the batter into a piping bag with a plain nozzle and pipe. Blitz some salted popcorn until it is fine and then sprinkle lightly over the shells. Allow the shells to stand for at least 30 minutes until they form a skin.Preheat the oven to 180 degrees and then put the shells in the oven and bake for 12 minutes. Personally, this temperature is too high for my oven, so you will need to figure out which temperature works best with your oven. However, most macaron recipes will set the temperature anywhere between 140 to 160 degrees and have the macarons baking anywhere between 15 to 20 minutes.To make the salted buttercream, bring the pouring cream to boil and then set it aside. Tip about 25gm of the caster sugar into a heavy based saucepan and allow it to melt (do not stir) and then add another 25gm and repeat 4 more times. Allow the syrup to caramelise to a very dark amber colour. Take it off the heat and add 37.5g of the salted butter. Stir with a spatula and then pour in the boiled pouring cream a bit at a time stirring continuously. Bring it back to the heat and continue heating until the cream reaches 108 degrees. Don’t worry if the caramel begins to solidify as when you begin heating it, it will smooth out again. Refrigerate the caramel cream until cool. Once cool, beat the remaining softened butter and then add the caramel cream half at a time. Pipe with a plain nozzle on half the macaron shells and top with the remaining shells.
