Quotations
Everyone should indulge in a formal afternoon tea at least once while in London. This relaxing, drawn-out, civilized affair consists of three courses, all elegantly served on fine china: dainty finger sandwiches (with the crusts cut off, of course); then fresh-baked scones served with jam and deliciously decadent clotted cream (the rich, thick cream is also known as Devonshire cream); and lastly, an array of bite-size sweets. All the while, an indulgent server keeps the pot of your choice fresh at hand.
