I've done quite a bit of research into the origins of this tart or pudding and it all seems very complicated! From what I can gather, the original Bakewell recipe has many claimants. One thing I do know is that a pudding or cake was sold in the town of Bakewell many years before the Bakewell Tart was supposedly first made. My recipe has no flour and relies on almonds and eggs to get a lovely pudding. The centre will sink considerably but that's quite normal.
