"The secret to a great sponge cake is air. Lots and lots of it. My 3 key tips to ensuring you incorporate as much air as possible are - 1. Triple sift your flour. Critical! 2. Eggs at room temperature. 3. Work quickly but very gently when folding flour through the batter with a thin rubber spatula. All you need to do now is file this recipe under 'tried and tested delicious family favourite'. Happy Sunday folks!"
