The uses for this simple berry sauce are endless. Add it to Greek yogurt for a decadent dessert (or breakfast), or serve it as an accompaniment to a chocolate pudding to cut through the richness. It’s a slightly healthier alternative to chocolate sauce on ice cream, and it can even work as a savoury relish, for example with duck. Prep time 5 mins Cooking time 1 hour Makes 500ml 500g mixed berries Caster sugar, to taste Water Lemon juice Place the washed berries in a saucepan and sprinkle the caster sugar evenly on top. Cover with water and add a squeeze of lemon juice. Cook over gentle heat, crushing the berries with a wooden spoon, until the sugar has dissolved. Blend the mixture with a hand stick blender and pass through a strainer if you want a very smooth coulis. Refrigerate until completely cool.
