I've created my own sauce, bagged it and left in the freezer for many days. It is still not frozen stiff (details to follow). I'm struggling to know how to phrase this question but, I'm concerned that since it's not frozen stiff that it's life is therefore reduced.
My freezer is to -18°C.
The ingredients are 300ml water, 100ml white wine vinegar, 2tsp tomato sauce, 2tsp plum sauce, 120g sugar and 2tsp corn flour.
I've Googled freezing white wine vinegar and corn flour to see if these prevent freezing (due to the alcohol in the vinegar and it was just a guess to search for corn flour) but my searches provided no answers.
So, my 2 questions are why does this mixture not freeze and does it affect the life it can remain in the freezer because it's not frozen or is the fact it's still in the very cold environment (-18°C) the thing which means it's safe for a month or two?
