How to turn a single egg and rescued berries into a classic British dessert

Strawberries and cream meets Eton mess, using just a single egg white and past-its-best summer fruit – a towering success

Just a single egg white can be transformed into enough elegant meringue shards to crown more than four servings of pudding, as I discovered when, earlier this year, I was invited by Cole & Mason to come up with a recipe to mark London History Day and decided to do so by celebrating the opening of the Shard in 2012. Meringue shards make a lovely finishing touch to all kinds of desserts, from a rich trifle to an avant-garde pavlova or that timeless classic, the Eton mess. As for the leftover yolk, I have several recipes, including spaghetti carbonara (also featuring salt-cured egg yolks that make a wonderful alternative to parmesan) and brown banana curd.
