The base here is a popular modern classic, the nettle decorated Cornish Yarg. The patterns made by the hand-applied covering of leaves are simply stunning. Sharpham's version of brie is next (the 1kg round), made using Jersey cows' milk from their farm by the River Dart.
Cornish Blue won Best English Cheese and Best Blue Cheese in 2006, which is all one needs to say about this sensational blue. Finally, Graeme Townsend's much-admired Vulscombe tops it all off.
There's about 5.8kg of cheese here: this might work for 55-60 or so people.
Pictured cake decorated by Annie Howes, but do remember that we don't include materials for decorating - so you'll need to find a creative person for this job!

If you'd like a larger version of this cake, take a look at Haytor, which adds a large wheel of cheddar.
