I am planning on making eggnog for the first time. I am from Australia where eggnog is not really a thing, and living in the UK where that still seems to be the case. This means I haven't grown up seeing how eggnog gets prepared and stored.
I am aware that some recipes of eggnog are made to be stored and aged for a week or more, sometimes a month or even several months. I plan to make some tomorrow to have on boxing day (so 14 days). If I were to make eggnog to be consumed in a day or two I imagine I'd just store it in a plastic jug, but what should I be using if I were to store it for longer?
The eggnog recipe on Alton Brown's website mentions storing it in glass jars. Should I be using mason jars, or jam jars with screw-on lids, or is either fine? Are there better/worse answers?
