When I made this cake it was for our annual street party, which was a happy, sunny event on a Friday evening, even if Little BB did try to scooter down our road/hill on a borrowed scooter several sizes to big for him. I even used blueberries picked from our very own blueberry bush (singular, one of them died) in our very own (patio) garden. Supplemented by some from Ocado – 250g is a lot of blueberries I soon discovered. Then at the weekend I made the mistake of reading an article about Japanese Knotweed, a plant so awful even the Royal Horticultural Society describes it as a thug, and ever since I have been obsessed by it, to the exclusion of almost all else. I see it everywhere. And I am afraid; very afraid. I have taken to inspecting our garden almost hourly to ensure it hasn’t crept in to destroy all the equity in our house and my dreams of one day moving to somewhere with two bathrooms. I scan hedgerows and paving slabs for sign of its insidious tentacles, lest they should spread towards my front door whilst I am sleeping. I know this is not normal, but I simply can’t be stopped. Much like the plant.
