Add Saskatoon Berries and Oregon Grapes to a medium saucepan. Add one cup of water and cover. Simmer for 15 minutes.
Mash berries with a potato masher, or spoon, then work to extract their juice using a sieve. I was able to get two cups of juice. If you get less, add enough water to equal 2 cups.
Return strained juice to the pot and add huckleberries. Boil for 10 minutes, stirring occasionally.
Add sugar, lemon juice, and spices. Boil for 20 minutes, or until the jam starts to thicken, stir occasionally. The jam thickens further upon cooling.
Ladle in sterilized jars, hand tighten lids, and process for 10 minutes in boiling water.
Place a small amount of jam in the fridge to see what the final consistency will be. If it's still too runny after 30 minutes in the fridge, boil the jam for 10 minutes longer.
If processed in hot water bath, this jam will last up to a year or longer when stored in the pantry.
