Wrapping Individual Traditional Christmas Puddings

This year I’ve made the Traditional Christmas Pudding in 8 mini tins because I want to give 5 as gifts. Delia says to wrap them in baking parchment & muslin - presumably after one has recovered the tops with double parchment & tin foil? One more question: I don’t remember from previous years that the steamer water & basin (tins in this case) were so greasy after steaming, as if some content had boiled over. Is this to be expected?
I don’t want just to ask daft questions at Christmas: in March, having been told to shield, I started to bake cakes for the first time (in common with most of the country) so I also wanted to thank you very much for your delicious recipes, which have played a big part in keeping us sane in this worrying year. We, and some privileged neighbours, especially love the Austrian Coffee & Walnut and the Coffee & Cardamon cakes. Many, many thanks.
