A mathematician claims to have devised a formula to create the perfect cream tea.
Rodda's, a family run creamery based in Cornwall, commissioned Dr Eugenia Chen from Sheffield University to create a formula that identifies the perfect ratio of scone, cream and jam used to make up a cream tea.
Dr Cheng's research found that:
- Clotted cream is better suited to a scone than whipped cream
- The total thickness of the scone should be around 2.8cm
- Jam must be spread before the application of the clotted cream due to its density
- The thickness of the cream should not be thicker than the scone because the scone may become unstable during the eating process
- A rim of around 5mm is required around the jam, to prevent mess, and then a further rim of 5mm for when the cream is placed on top of the jame
The mathematician compared the art of building a scone to constructing a good sandcastle, arguing that a wider base is required before the scone becomes narrower, to ensure stability and to avoid dripping.
Dr Cheng, who is renowned for using food to explain complicated maths to students, said:
The new formula will debut at the Royal Cornwall Show in early June.
Rodda's director Nicholas Rodda said the formula ensured the perfect cream tea could be produced "no matter where you are in the country".
