"Stephen's mother always made us a beautiful Midsummer cake - the whole family got some of it, but Rose and I never let others join in our rites on the mound ..."
What might Cassandra's cake have been? Food doesn't feature much in I Capture the Castle (and the family are actually often hungry) so there wasn't a lot to go on. Spoilt potato cakes and burnt porridge are hardly appetising, but happily the Cottons provide better fare for the impoverished Mortmains, including peaches they've sent over from Scoatney.
The fruit was the key for today's cake, and although here at the end of August we are two months past the longest day, we can still enjoy something redolent of that season; peaches are ripe, blueberries are easily found, so Nigel Slater's 'cake for midsummer' it is.
It could have been strewn with rose petals, as Nigel sometimes favours and Cassandra might quite like, but it's very good, just as it is (as is the book, I think!).
