This easy thimbleberry jam recipe lets the natural sweetness of the berries shine with less sugar, so you can fully enjoy their unique, vibrant flavor. Perfect for anyone looking for a simple and delicious way to preserve thimbleberries!
Rinse and search the thimbleberries for any bugs that might have snuck in while you picked them.
Put jars and lids in a large pot and cover with water. Bring the water to a boil and let it continue to boil while you cook the berries.
Add thimbleberries and sugar into a pot and set the heat to medium-low. Stir constantly until the berries let out their juices.
When the berries have released their juices add lemon juice and turn the heat up a little to medium/medium-high. Bring the mixture to a boil. Stir often so the berries don't stick to the bottom of the pan.
Boil for about 3 minutes and remove from heat.
Using a funnel, ladle the jelly into clean jars, leaving 1/4 inch headspace. Wipe the rims with a clean cloth and put the lids on. Tighten to fingertip tight.
Put the jars in the canner and lower the rack. The water should cover the jars by 1-2 inches. Add water if needed. Put the top on the canner and bring the water to a boil. Once it is boiling, process the jars for 10 minutes.
When the timer goes off, turn the heat off and let sit for 5 minutes. Remove the lid and remove the jars using a jar lifter. Let sit for 12-24 hours and then check for proper seals. Store in a cool, dry place with the rings off.
