Jamie Oliver’s Rhubarb and Ginger Jam is a classic fruit jam made by slowly cooking rhubarb with sugar and ginger until thick and glossy. The rhubarb breaks down naturally, while the ginger infuses warmth, creating a smooth jam with soft texture and bold flavour.
Wash and trim the rhubarb, then chop it into small, even pieces. Smaller pieces break down more evenly and help the jam thicken without long cooking.
Place the rhubarb in a large, heavy-based saucepan. Add the sugar, grated ginger, and lemon juice. Stir well and let the mixture sit for 10 minutes to draw out the natural juices.
Set the pan over low heat and cook slowly, stirring often, until the sugar fully dissolves. This prevents grainy texture later on.
Increase the heat and bring the mixture to a rolling boil. Cook for 15–20 minutes, stirring regularly, until the rhubarb has broken down and the jam thickens.
Spoon a little jam onto a chilled plate and let it sit for a few seconds. If it wrinkles when pushed with your finger, it’s ready. If not, boil for another 2–3 minutes and test again.
Remove the pan from the heat and skim off any foam from the surface. Let the jam rest for 5 minutes so the fruit distributes evenly.
Carefully spoon the jam into warm, sterilised jars. Seal immediately and allow to cool completely.
