Instructions
- 1
Place two small ceramic saucers into the freezer to chill for testing the set later.
- 2
Place the chopped rhubarb, granulated sugar, and lemon juice into a large preserving pan.
- 3
Add the grated fresh ginger, chopped stem ginger, ginger syrup, lemon zest, and ground ginger.
- 4
Leave the mixture to stand for 20 minutes until the sugar begins to dissolve into drawn juices.
- 5
Set the pan over low heat on the hob and stir until all sugar dissolves completely.
- 6
Increase the heat to high and bring the mixture to a rapid, rolling boil.
- 7
Boil vigorously for 12 to 15 minutes, stirring occasionally to prevent sticking.
- 8
Remove the pan from the heat and spoon a little jam onto a cold saucer.
- 9
Wait one minute, then push the jam with your fingertip to check if it wrinkles.
- 10
If it remains runny, boil for another 3 minutes and test again with the second saucer.
- 11
Stir in the butter to disperse any surface scum, then skim off remaining froth with a spoon.
- 12
Ladle the hot jam into warm sterilised jars, seal tightly, and leave to cool completely.
Chef's tips
Always ensure every grain of sugar is fully dissolved over low heat before bringing the pan to a boil. Rhubarb has moderate pectin, so the added lemon juice is essential for helping the jam achieve a proper set. Use young, pink stems for the brightest colour and sweetest flavour.
Ingredient substitutions
- stem ginger in syrup โ crystallised ginger, finely chopped
- granulated sugar โ jam sugar with added pectin
Storage
Store sealed jars in a cool, dark cupboard for up to one year; once opened, keep refrigerated and consume within four weeks.
Reheating
Serve at room temperature directly from the jar without reheating.
Common mistakes to avoid
- โขBoiling the jam before all sugar crystals dissolve, which causes the jam to crystallise in the jar.
- โขOvercooking the rhubarb, which can turn the preserve dull brown and make the fruit stringy.
- โขSkipping the saucer wrinkle test and ending up with an unset, runny preserve.
