This article outlines a recipe for a rhubarb and ginger jam, emphasizing a method that aims to preserve the vibrant red color of the rhubarb while creating a flavorful, slightly spicy preserve. The process begins with preparing the rhubarb, which involves washing and chopping it into small pieces, approximately 1-2 cm in length. The author suggests that peeling the rhubarb is generally unnecessary, especially for younger, more tender stalks, as the skin contributes to the jam's color and texture.
Once chopped, the rhubarb is combined with sugar. The ratio recommended is 700g of sugar for every kilogram of rhubarb. This mixture is then left to macerate, ideally overnight or for at least a few hours, to allow the sugar to draw out the moisture from the rhubarb. This step is crucial for developing the jam's flavor and ensuring a good set. During this maceration period, the rhubarb will release a significant amount of juice, forming a syrupy mixture.
The next stage involves preparing the ginger. Fresh ginger is peeled and grated or very finely chopped. The amount of ginger can be adjusted to personal preference, but the recipe suggests a quantity that provides a noticeable "fiery" kick without overpowering the rhubarb. The prepared ginger is then added to the rhubarb and sugar mixture.
The cooking process begins by gently heating the rhubarb, sugar, and ginger mixture in a large, heavy-bottomed pan. The initial heating should be slow to ensure the sugar dissolves completely before the mixture comes to a boil, preventing crystallization. Once the sugar has dissolved, the heat is increased, and the jam is brought to a rolling boil. The author stresses the importance of maintaining a vigorous boil to achieve the desired setting point quickly, which helps to preserve the fresh flavor and color of the rhubarb.
To test for the setting point, several methods are described. One common technique involves placing a small spoonful of the hot jam onto a chilled plate. After a minute or two, if the jam wrinkles when pushed with a finger, it has reached its setting point. Another indicator is the temperature; a jam thermometer should read around 104-105°C (219-221°F). The author also mentions the "flake test," where a spoonful of jam is lifted from the pan, and if it drips off in a sheet or flake rather than individual drops, it's ready.
Once the jam has reached its setting point, it is removed from the heat. The author suggests allowing the jam to cool slightly in the pan for about 10-15 minutes before jarring. This brief cooling period helps to distribute the fruit more evenly throughout the jars and prevents the fruit from sinking to the bottom.
Sterilization of jars and lids is a critical step for ensuring the jam's longevity. The article advises washing jars thoroughly in hot soapy water, rinsing them, and then sterilizing them in an oven at a low temperature (around 120°C or 250°F) for at least 15-20 minutes, or by boiling them. Lids should also be sterilized, typically by boiling them for a few minutes.
Finally, the hot jam is carefully ladled into the warm, sterilized jars, leaving a small headspace at the top. The lids are then securely fastened. As the jam cools, a vacuum seal will form, indicated by the lid "popping" inwards. The finished rhubarb and ginger jam is described as having a vibrant color, a balance of sweet and tart flavors from the rhubarb, and a warming, spicy note from the ginger, making it suitable for various culinary uses.
