On my last trip to London, I was lucky enough to happen upon Bea's of Bloomsbury. Unfortunately, we didn't have enough time to do the full-blown afternoon tea when I was in London, but the scones at Bea's definitely made up for it. I was so excited to try the scones there that I ran to the grocery store to buy some marmalade and clotted cream. The crumb was so soft that the scones tasted like cake with the clotted cream. The crust was perfectly brown and added a nutty flavor which contrasted perfectly with the delicate interior.
The owner of Bea's of Bloomsbury also just came out with a cookbook. I think I'm going to buy it just so that I can get the scone recipe.
