BBC Two’s Inside The Factory documentary series took a look at a Premier Foods cake facility this week.

TV presenter Gregg Wallace visited the factory in Stoke-on-Trent to see how its Cherry Bakewells were made, meeting the team of 12 employees who put the cherries on top.

It was revealed that Mr Kipling owner Premier Foods produces 250,000 Cherry Bakewells a day, with Wallace following the process, from the arrival of 27 tonnes of flour through to dispatch.

Co-presenter Cherry Healey learned how to avoid a soggy bottom when making pastry at home, using a pre-heated oven, a specific thickness of pastry and blind-baking. She also visited another factory where almonds are roasted and milled to make butter.

Historian Ruth Goodman discovered the origins of frangipane and learned how the modern cherry Bakewell recipe came about.

The programme is still available to view on BBC iPlayer.
