white stuff on marmalade

  • c

I have a jar of orange marmalade that I haven't used in months.....it's been in the fridge. Today I opened the jar & I saw a lot of white stuff on the surface. Is is only sugar? And if it is, how does the sugar go thru the jelly? Or is it something more ominous?

  1. If the jar was opened before it could be mold. If someone put a spoon in it that had something else on it, or licked it, otherwise, my guess is it could be sugar, similar to when honey crystalizes on top.

      That's what I think....that it's sugar, because I'm the only person here & I'm very careful about putting clean utensils into a jar of anything.

        If it's crystalline, it's just sugar... if it's soft and fluffy or furry-looking, it's mold.

          I have a jar of lime curd and a jar of orange marmalade in my fridge right now that have white lumps all over the surface - and yes it is sugar. It takes us so long to go through a jar that they mostly all end up looking like that. I'm pretty sure that in crn's case it's sugar too. In my case I think it was accelerated because both jars ended up getting frozen for a while (fridge mishap).
