I'm taking Christmas dinner to an older lady who will be on her own on Christmas Day. She lives a short drive away. I'm trying to work out the practicalities of how best to transport it, as in what to put it in. Plate it up? Put the different bits in different containers? Put all of it in one thing? It doesn't need to stay ready-to-heat hot, I'm anticipating she will want to warm it up. Any great tips? Thanks in advance.
