This is a perfect and pretty Christmas gift or looks great as an apéritif for your Christmas meal with family. The difference between the traditional Rumtopf and plum brandy is that the Rumtopf is fermented - personally I prefer this traditional Germanic style, but both taste great and take seconds to make (although you do need to leave them 3 months before they are ready)
1. Pick then wash the plums, then cut them in half and twist out the stones. You can use a plum stoner but it's prettier if you do it by hand as you can see the neatly sliced plums through the sides of the Kilner jars when you have bottled them.
