Haskap berries, sugar, and lemon juice are all you need to make a sweet and tart haskap jam. No added pectin required for this special Canadian summer treat!
2tbsplemon juice(*can sub with 1/2 tsp citric acid; see Note 2)
Instructions
Add 1 lb of haskap berries and 1/2 lb of sugar to a non-reactive pot.
Turn the stove on to medium heat. As the pot heats up, mash the berries and sugar together until the sugar melts into the berries. Don’t worry if the berries are still mostly whole at this stage; they will break down on their own as they continue to cook.
Stir continuously for around 30 minutes; towards the end of cooking, test the jam with a food thermometer. Take it off the heat when the thermometer reaches the gelling temperature (see Note 3).
Stir in 2 tbsp of lemon juice or 1/2 tsp citric acid powder. When the jam stops bubbling, transfer it into glass jars. You may either can it for longer storage or just keep it in the refrigerator for up to a month.
Let cool fully before using.
Notes
Pot: Use a non-reactive pot to avoid the taste of metal transferring into your jam. Other materials like copper, bare cast iron, and aluminum are considered “reactive” and the acid in the jam will eat away at the lining of the pot, giving a tinny flavour.
Acid: Use 2 tbsp of bottled lemon juice, 3 tbsp of natural lemon juice, or 1/2 tsp of citric acid powder for 1 pound of fruit.
Temperature: The gelling temperature is the temperature your jam needs to reach before you take it off the heat, and it depends on your altitude. Refer to the gelling temperature chart to see what temperature you should use at your location.
