The episode: “The Projected Man,” ep. 901
The riff: Said slyly by Mike as one British scientist casts a sideways glance at one another while they watch their experiment explode in front of them.
The explanation: Clotted cream is a type of dairy product made by indirectly heating cow’s milk and skimming off the “clots” of cream that form on the surface. It is eaten in a variety of ways but is especially important in Britain as a part of a traditional “cream tea.” That isn’t tea with cream in it, but rather a teatime set-up that includes tea and scones, which are then spread with clotted cream and fruit jams or preserves. Naturally, the British disagree strongly on which preserves are correct to use.
Novelty factor: I can’t say I’ve ever heard of clotted cream in my life, but I find myself wondering now what it tastes like.
