I’ve never done a relish that wasn’t a preserve. That means the contents have been fermented or sterilized in some fashion. What you’re making is similar to a chutney, except my chutneys are all spicy. I like spicy sweetness to add to my curries.
The acid in the citrus and cranberries will give your chutney some shelf life in the fridge, but not that much. Psychrphilic fungus and molds can and will grow on the surface of your mixture. If you could vacuum pack them you could keep the wee beasties at bay permanently, but that isn’t an easy thing to do.
I wouldn’t set something like this up unless I was going to use or give it away very, very quickly. And I wouldn’t give it away to anyone who wasn’t well versed in looking for signs of spoilage. I definitely wouldn’t freeze anything with fresh fruit, it ruins the texture.
Sorry not to give the answer you want. I spent a crapload of my day making and canning salsa. To my mind preserves are not a thing in which one takes half measures. No one ever died from eating cookies.
Ah, see I knew you'd know something about this. The acidity is why I thought it would last longer, I've got a pH meter and it's 2.8.
I do have the vacuum pack device, hadn't thought about doing that, but no, it would be messy and a chore and the presentation not what I want.
Everyone I'm giving it to are people well known to me, that's not a problem. I will be able to hold off giving it to them until they are home and it can go immediately from my fridge to theirs. I might ship some to family members (people who would not hold it against me if I poison them) but for those I'll definitely freeze it and then pack it in dry ice and ship overnight.
I did give hubby a taste test, some I had frozen and thawed, and some fresh. He could not tell the difference. I was sure it would destroy the quality but it didn't seem to. Maybe cranberries have a structural strength over most other foods?
In any case I think it's unanimous, for fresh, two or three week old is too old. Even if it stays good, I just don't feel right about it. I will either have to freeze it, or make it the week of Christmas. My whole worry was the cranberries will be gone by then but maybe I can talk to the store and have them order/reserve them for me.
Thanks for all the input guys. Next year I'm going back to Mrs. Hanes Moravian cookies. This is just too much trouble.
