Instructions
Prepare the ingredients
Chop the rhubarb and strawberries. If using frozen blueberries, thaw them first.
Combine fruits and sugar
In a large pot, combine rhubarb, strawberries, blueberries, and sugar. Stir to mix evenly.
Pro tip: Let the mixture sit for a few minutes to help the sugar dissolve.
Cook the mixture
Place the pot over medium heat. Cook while stirring until the sugar dissolves and the mixture begins to simmer.
Simmer the jam
Reduce the heat to low and let it simmer for 20-25 minutes, stirring occasionally, until the mixture thickens.
Pro tip: Use a spoon to remove any foam that forms on top.
Add lemon juice
Stir in the lemon juice and continue to cook for another 5 minutes.
Pro tip: Lemon juice helps to enhance the flavour and acts as a natural preservative.
Check for doneness
To test if the jam is done, place a small spoonful on a cold plate. If it wrinkles when pushed, it's ready.
Pro tip: If not set, cook for an additional 5 minutes and test again.
Sterilize jars
While the jam is cooking, sterilize your jars by boiling them in water for 10 minutes.
Fill the jars
Carefully ladle the hot jam into the sterilized jars, leaving about 1 cm (1/2 inch) headspace.
Seal the jars
Wipe the rims clean, place the lids on, and screw the bands until fingertip tight.
Pro tip: Invert the jars briefly to ensure a good seal.
Cool and store
Let the jars cool at room temperature. Store unopened jars in a cool, dark place.
Tips & Tricks
- Use fresh or frozen berries for convenience.
- Add a splash of lemon juice for brightness.
- Ensure jars are sterilized before use.
