I find jellies help with clumps, at least. Idk about anything else!
My FSG has never gone bad. I do keep it refrigerated, tho. We have a mini-frig upstairs, and I keep it in there. I think between that and all the additives I use that have preservatives in them, I never run into a problem.
The actual "making" of it wasn't as bad as I expected, tbh. Even with two little ones running around at my feet!
