At the local markets here in Zurich you can get old carrot species. I wondered if these sorts were aswell suitable for carrot cupcakes. So I decided to go with the yellow ones.
It showed that they have a different structure, because I had difficulties to grate them. They were more fiberous and less juicy. So I grated them in two rounds.
I decided to combine two recipies: Carrots, Oranges and Rum Raisins with cream cheese frosting.
