Heat the sour cherries and their juice strongly, but do not let them boil. Add mulled wine spice and let steep for 15 minutes, then remove the bag again. Add the amaretto, puree the mixture, stir in the preserving sugar and simmer for about 10 minutes. Make a gelling test and then fill into jars and close.
My tip: is very suitable for Christmas cookies such as angel eyes or terraces.
