Russian nozzle piping tips create a gorgeous ruffle finish, and due to their design are ideal for decorating cupcakes with eye-catching swirls in a single swift motion. To use them, simply fill your piping bag with a firmer icing (such as buttercream or Swiss meringue) and decide whether you're going to pipe directly onto your cake, or onto a piece of baking paper. Always start with a practise squeeze to ensure the frosting is evenly dispersed within the bag and comes out the tip easily. For the real deal, hold the Russian piping tip just above the surface you're working on with the nozzle pointing down, and apply steady pressure to the bag whilst pulling upwards as steady pressure. When your frosting is at three quarters of your desired size, release the pressure and pull upwards until the frosting separates from the tip. Et voila!
