I have had many requests for macaron recipes lately, and thought I'd share this quick and easy macaron shell recipe. It's great for when you need to make macarons in a hurry, but unfortunately doesn't make very many (~20).
110g ground almonds
200g icing sugar
50g caster sugar
90g egg whites
colouring of your choice
Whisk egg white to stiff peaks, gradually adding the caster sugar. Add colouring to achieve intensity you desire.
Fold almonds and icing sugar into the eggwhites, "macaroning" until you achieve the correct consistency.
Pipe rounds onto baking trays and leave until a skin forms (usually at least 30 mins, much longer if humidity is high).
Bake at 150 deg C for 12-13 mins, cool and remove from trays.
Sandwich with your desired filling.
