The Mary Berry Shortcrust Pastry Recipe for sweets is a foolproof recipe perfect for her Bakewell Pie, Apple and Pear Pie and the famous Strawberry and Rhubarb pie. This pastry calls for just four main ingredients: plain flour, chilled butter, icing sugar, and a large egg. The addition of icing sugar gives the pastry a slightly sweet flavour, making it perfect for desserts like fruit tarts or pies.
