Place the orange and lemon slices in the pan. Pour the coffee into it and put it on the fire. When the mixture comes to a boil, pour in the rum and a splash of sugar.
Stir to dissolve the sugar. Remove from the heat immediately afterwards. While the coffee is still hot, pour it into glasses and garnish them with lemon wedges.
Tip: This drink is made with medium strength coffee. Any degree of roast is fine, but coffee that is too dark will ruin the taste of the rum and citrus.
