Hola!
I was thinking about conserving this plums from this season in some alcohol (19%) for christmas and making it into a sort of jam/chutney. As I want to boil down/reducing the jam in christmas, and then add some fresh alcohol (both to give it some alcohol flavour after reducing it, and also to make it easier to control the alcohol flavour for the final product). So I thought it would be best to use as little alcohol (now) as possible, by blending the plums, add some alcohol and then put the mix into a sealed and vacuumed bag (for storing). So my questions are:
1. Does this seem like a good approach?
2. How much alcohol (19%) do I have to add, relative to plums, so it won't rot or something like that?
3. Should I store it in the fridge or room tempered?
