clotted cream

Do you really want to buy clotted crab? Doesn't sound very healthy.

Whenever I've gone to Devon I've noticed the sign 'Clotted Cream by post,' in a lot of shops.

Googling the phrase brings up these search results.

Your best bet is to google the phrase, there's a lot more than the above results.
