I've developed this recipe for rhubarb cake when I was working at Down House - a historic house in Kent where Charles Darwin lived for most of his life. We had an amazing garden kitchen which also had a large patch of heritage rhubarb. I wanted to create a recipe that would use the rhubarb as the main ingredients, as we had a bounty of rhubarb every year.
Each day during the rhubarb season, I would walk down to the end of the garden after I finished my work and cut few stems of rhubarb. I was under strict instructions to make it look like 'nothing was missing', so I would spend a lot of time working out how to cut the best stems that were ready from each cluster. Fortunately the head gardener was a great fan of the rhubarb cake!
