Here are two variations on a strawberries and cream theme, which make simple and refreshing puddings for warm days. Long, thin langues de chat biscuits are a perfect accompaniment for either: they look smart, and are easy to make. A piping bag is necessary to achieve the narrow shape which gives the biscuits their name, but no-less-pretty oval biscuits can be made by shaping the mixture with two teaspoons. It is the butter that gives them their rich flavour, so be sure to use best quality, and unsalted.
