In our new mini-summer-series, we’re asking “What’s in your Rumtopf?”. A rumtopf, for those not in the know, is a straight forward summer-fruit preserve consisting of fruit, sugar and overproof rum. It’s an old tradition, with origins in Germany and naturally, variations abound. There are versions that use brown sugar and dark rum for added notes of treacle and caramel, where some opt for gin or brandy in place of rum to suit personal spirit preference. Almost any combination of fruit will work and indeed no combination at all—no one is going to balk at a rumtopf made up solely of sour cherries and brandy though maybe just don’t call it a rumtopf.
Our rumtopf, apart from not using a proper rumtopf crock, will be retaining its rumtopf purity with a mixture of fruit as it comes into season, white granulated sugar, and overproof white rum. The proportion to keep in mind is that you’ll be adding half the weight of whatever fruit you add with sugar (500g of strawberries = 250g sugar). Top each addition with just enough spirit to cover. As another fruit comes along, add it in and repeat with sugar and rum. Make sure to wash and sterilize your rumtopf vessel before beginning.
By the end of it, what you’re left with is some boozy preserved fruit in a homemade cordial. Preserving in alcohol may be the easiest method but it’s also one of the slowest, meaning this rumtopf won’t be ready until Christmastime, at which point the fruit can be eaten alongside cake or on top of ice cream and the cordial mixed into a cocktail or sipped straight up.
So, what’s in our rumtopf this week?
