Edd Kimber's Italian Meringue Buttercream
This is a proper buttercream, made with egg, boiling sugar syrup and butter. You’ll find it’s beautifully smooth, not too sweet and perfect for frosting cakes or cupcakes. However, to get it right you must have the temperatures spot on.
Edd Kimber, Great British Bake-Off 2010 winner says he couldn’t do without his Thermapen because he relies on the simple-to-use digital food thermometer to give an accurate and near instant reading.
