Those poor Dunnetts! Pop over to Dovegreyreader Scribbles and Lynne will tell you their story, but from the victuals point of view The Children who Lived in a Barn is a sorry tale. They do their best, of course, but rations are meagre so there's a bit of reliance on bread and butter or dripping, the occasional egg, and then the famous haybox, the equivalent of the Aga's simmering oven, by which they manage a rabbit stew and overnight porridge.
Village neighbours do help, for instance kind Mrs. Dew gives the children "a lovely golden brown cake with pieces of peel sticking up through the surface". I took her gift as my starting point, but went a step further and decided that Eccles Cakes containing peel along with the spiced currants might be just the thing for this month's Persephone tea, and had she had them to hand (and remembering always to 'eat fair'), Susan could have packed one or two to take with her when she went on strike and fatefully met Alastair Grant.
The recipe I used was from The Ordinary Cook (do have a look at all the good things there), and they've turned out beautifully; 500g of pastry yielded fifteen, and there's some filling left over.
