Hot redcurrant and raspberry mousse | The Proof of the Pudding

This is an absolute killer of a recipe. It’s perfect for a dinner party or special weekend meal because it tastes divine and looks both appropriately impressive and ridiculously pretty, but is actually very simple to make. It does require a little last minute work, but you can prepare steps 1 to 3 in advance and then spend less than 10 minutes in the kitchen between the main course and pudding.

This recipe comes from Summer Cooking by Elizabeth David, one of the highest members of the royal family of cookery writers. It’s a retro-looking book that’s been sitting on my parents’ shelves for decades, but it’s packed with gorgeous seasonal recipes and this is one of the best. This is barely altered from the book – the only change is that we heat the berries before squeezing the juice from them as it makes it easier to extract the maximum amount.

This is our go-to recipe for a fancy dessert during the summer months when my dad’s allotment provides a glut of redcurrants and raspberries, though the beauty of it is that if you freeze the berries when they’re at their peak you can have a taste of summer all year round. A word of warning before we start: you really want an electric whisk for this recipe. Believe me, it’s extremely hard to achieve the right consistency with a hand whisk; even my mum, who is vehemently against the use of an electric hand whisk, admits it is necessary for this one dish!
