To ensure a smooth texture, make sure all the frozen berries are completely thawed before starting the recipe. For a slightly chunky jam, mash some of the berries with a spoon as they cook. Always sterilize jars properly to prevent spoilage and extend the shelf life of your Christmas Jam. If you prefer a sweeter jam, you can add an extra half-cup of sugar.
