Marmellata is the word used in various European languages to denote a jam, rather than the specific usage in English, to denote a preserve made from oranges. I have made a chestnut ‘jam’, and here there is one made from sweet beetroots, perfect for breakfast or afternoon spreading: it would be perfect used as the filling for my carrot cake.
The ‘jam’ could also be made with carrots. Neither of them last long, though, so use as soon as you can.
