This is a thimbleberry bush...large soft, fuzzy leave with red fragile berries.
This is a typical berry...red, fragile, tea cup shaped.
Critters like thimbleberries. I recommend "picking clean" (leaving debris and bugs aside while you pick). At home, spread out the berries in a single layer, picking out debris and bugs. Rinse & dry.
Get a pretty good measurement of your berries.
Dump clean, dry berries into a heavy saucepan.
Use equal amounts of berries and sugar. I had roughly 1 cup of berries. (Yes, I know this is a liquid measuring cup. This recipe doesn't call for precision 😉)
Pour sugar into the pan with the berries.
I use a subtle "stir mash" motion to mix the berries and the sugar.
Over medium heat, stir/mash the berries until the sugar is completely melted. Stir constantly & bring to a low boil.
When your jam reaches a low boil, turn heat to low, keep stirring. I do this for a couple minutes to make sure sugar is melted & to kill anything that might still be living on the berries.
At this point the jam will have the consistency of thin yogurt. It'll be slightly foamy on top too.
Done! I never have enough berries to make it to the jarring phase. These berries are hard to come by & have a short season. I pick 1-2 cups and make jam immediately. This bowl will be empty in a day!
