A Rumtopf is made by steeping fruit or berries in rum. When it's complete, you can bottle the liquid and serve it as a liqueur or cordial, and the fruit can be used to bake in a pie or served over ice cream.
The Pennsylvania Germans brought this recipe with them to our neck of the woods. I've been making batches for over 20 years, mostly with mulberries, which grow all over my corner of Pennsylvania.
1 kilo fruit or berries, thoroughly washed and rinsed, fruits cored or pitted as necessary and cut into pieces; berries like mulberries, raspberries, blackberries, etc, can be used whole
500 g sugar
juice of one lemon
3 L dark rum, at least 100 proof or stronger
In a bowl, toss the fruit or berries with the sugar to cover all pieces. Place the fruit and sugar in a large glass container. A jar with a spring closure and a rubber gasket is best. Add the lemon juice and the rum and stir till the sugar is dissolved.
Set the jar in the cellar or some other cool place and let the mixture steep for at least 6 weeks. The longer it steeps, the more the juices blend and the mixture mellows. Stir the mixture once a week.
After 6 weeks or when you decide the liquid suits your taste, decant the liquid into clean bottles. I use clear 750 ml wine bottles, but also old stone schnapps or mineral water bottles. Refrigerated, the Rumtopf keeps for years.
The fruit can be used in pie recipes or served over ice cream. You may need to rinse it, if the alcohol taste is too strong.
Some people make a Rumtopf of mixed fruits, adding each as it comes in season over the summer, but I like to make separate batches, one for each kind of fruit or berry.
I once made a batch of peach Rumtopf and added a cinnamon stick, and hickory nuts, which are also common around here. The cinnamon and nuts imparted their flavors to the liquid, which made an interesting and tasty flavor. You could try other spices, and nuts like walnuts, pecans or almonds, for different flavors.
