Strawberries that are either under-ripe and lacking in sweetness or overly soft and blemished often end up discarded. However, a simple culinary technique can transform these less-than-perfect fruits into a delicious no-churn ice cream, offering a practical solution to food waste in the kitchen.
The key to this transformation lies in roasting the strawberries. This process has a dual benefit: it intensifies the fruit's natural flavour by caramelisation and dehydrates them, reducing their water content. For under-ripe strawberries, roasting with a sweetener like maple syrup or honey can enhance their flavour profile, while for over-ripe fruit, it helps cook away any unappealing soft spots. The reduced water content post-roasting is particularly important for ice cream, as it minimises the formation of ice crystals, resulting in a significantly smoother and creamier texture.
The recipe for this no-churn ice cream combines the roasted strawberries with cold double cream, condensed milk, vanilla extract, and a pinch of sea salt. An optional tablespoon of a neutral spirit, such as vodka, gin, or white rum, can be added. This addition, along with the sugar from the condensed milk, helps to lower the freezing point of the mixture, contributing to a softer, more scoopable ice cream. Whipping the cream to stiff peaks before folding in the other ingredients is crucial for adding volume and achieving the desired light and airy texture.
To prepare the strawberries, they are halved, drizzled with sweetener, and roasted in an oven at 210°C (190°C fan)/Gas 6½ for 20-30 minutes until they begin to shrivel and caramelise. After cooling and chilling, they are gently folded into the whipped cream mixture. The ice cream then needs to freeze for at least five hours in an airtight container, with a sheet of greaseproof paper pressed directly onto the surface to prevent freezer burn. For optimal serving, it's recommended to transfer the ice cream from the freezer to the fridge for 45 minutes to an hour before scooping, allowing it to soften to a perfectly creamy consistency.
This method not only creates a delightful dessert but also champions the principle of 'waste not, want not', encouraging households to make the most of their produce. By repurposing strawberries that might otherwise be thrown away, consumers can enjoy a homemade treat while contributing to a reduction in household food waste.
