Jamie Oliver’s blackberry coulis is a smooth fruit sauce made by cooking blackberries with sugar and then blending and straining the mixture to achieve a silky texture.
Optional additions:
Add blackberries, sugar, and water to a saucepan. Cook over medium heat for 5–7 minutes until the berries soften and release juice.
Remove from heat and blend until smooth using a blender or hand blender.
Pass the mixture through a fine sieve to remove seeds, creating a smooth coulis.
Stir in lemon juice to balance sweetness and enhance flavor.
Let it cool before serving or storing.
