Halfing recipes does not always work out as planned. Did you half the egg, extra liquid will effect the dough. If could also be due to the thickness or thinness of the heavy cream. Mine is really thick. So adjust accordingly. Add flour a tablespoon at a time, Don’t just add a cup and think it’ll work. Scone dough is sticky, flour your hands and pat the dough into place. It will not be smooth like cookie dough. And when there are additional ingredients it won’t be just like my basic cream scone but this recipe with cranberry sauce was not difficult to roll into a ball as you can see in the photos.

I used a full cup of cranberry sauce in the dough. The remaining amount in the can, I used in the icing.
