Edit: to add, the jar was properly sealed when I opened it.

    That’s what you get with berries concentrate (a supply-chain thing) and sugar.

    But not so with self-made jam. Mold hates acidic environments. The jam rather dries out than getting moldy.

        What jam is it? My mom is a farmer and makes all kinds of jam, never saw mold there the last 30 years.

          All sorts really. She’s a farmer also. She gives me a lot and I tend to forget them in the fridge. I can tell you plum jam has mold.

          She adds little sugar, maybe that’s a reason.
